Cellular respiration and photosynthesis are two very important metabolic pathways necessary for life to exist. They are exact opposite chemical reactions from each other. Photosynthesis occurs only in plants and some bacteria while cellular respiration occurs in many different organisms including plants and animals.
The key purpose of photosynthesis is to make food for the plants, plants do not need to "eat" the way animals do, they can make food from the energy found in the sun, and this process is called photosynthesis. The key purpose of cellular respiration is to obtain energy from food products. This is why they are exact opposite reactions; photosynthesis takes energy from the sun and This solution describes the chemical reactions involved in cellular respiration and photosynthesis.Cellular Respiration 1 - Overview
It discusses the overall chemical equation for these two processes, compares and contrasts the reactants needed and the products produced from each process as well as discusses the role of ATP and the cellular organelles involved. State which one it is.
Add Solution to Cart Remove from Cart.The key difference between photosynthesis and cellular respiration is that photosynthesis utilizes carbon dioxide and water to produce glucose and oxygen while cellular respiration utilizes glucose and oxygen to produce energy, carbon dioxide, and water. Photosynthesis converts the light energy of the sun into chemical energy of sugar by releasing oxygen as a byproduct. On the other hand, cellular respiration is a biochemical process by which cells obtain energy from the chemical bonds of food molecules.
Photosynthesis and cellular respiration are key processes of life. This article highlights the difference between photosynthesis and cellular respiration. Overview and Key Difference 2.
What is Cellular Respiration 4. Similarities Between Photosynthesis and Cellular Respiration 5. Photosynthesis is a process that is carried out by photoautotrophs. Photoautotrophs produce their own food by this process. Plant, algae, and cyanobacteria are the main groups of photoautotrophs. During photosynthesis, using the light energy of sunlight, carbon dioxide, and water transform into glucose and oxygen when photosynthetic pigments are present. Photosynthesis is a very crucial process which allows life to continue on earth.
Oxygen produced through photosynthesis is essential for the process of respiration of most living creatures on earth. Carbohydrate produced by photosynthesis is the simplest form of food that could be processed by living organisms to obtain energy.
The following equation is the most common form of summarizing photosynthesis:. Photosynthesis can be divided into two main processes: light dependent light reaction process and light independent dark reaction process. Light-dependent photosynthesis needs actual sunlight to react, whereas dark reaction only needs the products of the light reaction to proceed.
NADPH is a reducing agent that can reduce its hydrogen molecule. Dark reaction photosynthesis, also known as the Calvin cycle, use Carbone dioxide and the newly formed NADPH to produce phosphogylcerides; the three carbon sugars could combine later to form sugar and starch.
Plants store these produced sugar and starch in the forms of fruits and yams, etc. Most other living organisms depend on these carbohydrates produced by plants through photosynthesis. Hence, photoautotrophs serve as primary producers in almost every food chain in an ecosystem. Cellular respiration is a biochemical process by which cells convert the chemical energy of macromolecules into energy in the form of ATP.
Cellular respiration uses carbohydrates, fats, and proteins as fuels.Photosynthesis is the process used by plants and some bacteria to create energy from sunlight. Chlorophyll is the green pigment in plants that is responsible for this conversion process. In all other living things, they rely on the process of respiration to stay alive. Respiration is the process of taking oxygen from the air and cycling it through the lungs, which then gives oxygen to blood to be used in the body.
The carbon dioxide waste is expelled out of the lungs. Cellular respiration uses glucose, or sugars, from food molecules and turns them into carbon dioxide, water, and ATP a nucleotide essential to the body. Photosynthesis converts light energy into chemical energy, and stores it in sugar. This process occurs in the chloroplastsusing chlorophyll. The chemical formula for the process requires six molecules of carbon dioxide and six molecules of water plus the energy from light.
This creates a sugar chain and six units of oxygen. Chlorophyll is green because the light required for photosynthesis is red and blue light, leaving green light to be reflected back to our eyes.
Photosynthesis occurs in the leaves of plants with little to none in the stems. Plant leaves are made of upper and lower epidermises, mesophyll, veins, and stomates. Mesophyll is the layer of the plant that contains chloroplasts and is the only place photosynthesis occurs. The energy taken is stored as ATP adenosine triphosphate. It is required for energy storage and is made of the nucleotide adenine with ribose sugar.
The respiratory system allows living creatures that are not plants to obtain oxygen from the air for use in the blood and cells. Oxygen is a much needed nutrient and living organisms can roughly only survive for minutes without it.
Even if oxygen flow is reestablished, the damage can be irreparable. Alveoli are responsible for exchanging oxygen rich air with carbon dioxide rich blood cells. Diffusion occurs due to the pressure difference between alveoli, which is high, and the pressure of blood, which is lower.
Blood cells take the oxygen and alveoli take the carbon dioxide, which is then exhaled. Cellular respiration first breaks down glucose into pyruvic acid, and then the pyruvic acid is oxidized into carbon dioxide and water.
This process usually occurs in the cytosol and mitochondria of eukaryotic cells. Mitochondria are organelles responsible for the conversion of potential energy into ATP. The main difference between photosynthesis and respiration is where it occurs, one being in plants and some bacteria and the other being in most every other living thing.
The other difference is that plants require sunlight for the process to occur, whereas respiration does not. But there is an important mutual relationship between the two processes because of the ingredients required, and bi-products produced. If plants take carbon dioxide and expel oxygen, and most other living things take in oxygen and expel carbon dioxide, the importance of both systems working in unison is obvious.

Copyright Leaf Group Ltd.Aerobic respiration, anaerobic respiration and fermentation are methods for living cells to produce energy from food sources. While all living organisms conduct one or more of these processes, only a select group of organisms are capable of photosynthesis which allows them to produce food from sunlight.
However, even in these organisms, the food produced by photosynthesis is converted into cellular energy through cellular respiration. A distinguishing feature of aerobic respiration as compared to fermentation pathways is the prerequisite for oxygen and the much higher yield of energy per molecule of glucose.
Glycolysis is a universal beginning pathway conducted in the cytoplasm of cells for breaking down glucose into chemical energy. The energy released from each molecule of glucose is used to attach a phosphate to each of four molecules of adenosine diphosphate ADP to produce two molecules of adenosine triphosphate ATP and an additional molecule of NADH. The energy stored in the phosphate bond is used in other cellular reactions and is often regarded as the energy "currency" of the cell.
Difference Between Photosynthesis and Cellular Respiration
However, since glycolysis requires the input of energy from two molecules of ATP, the net yield from glycolysis is only two molecules of ATP per molecule of glucose. The glucose itself is broken down into pyruvate during glycolysis. Aerobic respiration occurs in mitochondria in the presence of oxygen and yields the majority of energy for organisms capable of the process. Pyruvate is moved into mitochondria and converted to acetyl CoA, which is then combined with oxaloacetate to produce citric acid in the first stage of the citric acid cycle.
Each turn of the Krebs cycle is capable of producing one molecule of ATP, and an additional 17 molecules of ATP through the electron transport chain.
Since glycolysis yields two molecules of pyruvate for use in the Krebs cycle, the total yield for aerobic respiration is 36 ATP per molecule of glucose in addition to the two ATP produced during glycolysis.
Not to be confused with anaerobic respirationfermentation occurs in the absence of oxygen within the cytoplasm of cells and converts pyruvate into a waste product to produce the energy carrying molecules needed to continue glycolysis.
Since the only energy produced during fermentation is through glycolysis, the total yield per molecule of glucose is two ATP. While the energy production is substantially less than aerobic respiration, fermentation allows the conversion of fuel to energy to continue in the absence of oxygen.
Examples of fermentation include lactic acid fermentation in humans and other animals and ethanol fermentation by yeast. The waste products are either recycled when the organism re-enters an aerobic state or removed from the organism.
Found in select prokaryotes, anaerobic respiration utilizes an electron transport chain much as aerobic respiration but instead of using oxygen as a terminal electron acceptor, other elements are used. These alternate acceptors include nitrate, sulfate, sulfur, carbon dioxide and other molecules.
These processes are important contributors to the cycling of nutrients within soils as well as allowing these organisms to colonize areas uninhabitable by other organisms. Unlike the various cellular respiration pathways, photosynthesis is used by plants, algae and some bacteria to produce the food needed for metabolism.
In plants, photosynthesis occurs in specialized structures called chloroplasts while photosynthetic bacteria typically carry out photosynthesis along membranous extensions of the plasma membrane. Photosynthesis can be divided into two stages: the light-dependent reactions and the light-independent reactions. During the light-dependent reactionslight energy is used to energize electrons removed from water and produce a proton gradient that in turn produces high energy molecules that fuel the light-independent reactions.
As the electrons are stripped from water molecules, the water molecules are broken down into oxygen and protons. The protons contribute to the proton gradient but the oxygen is released. During the light-independent reactions, the energy produced during the light reactions is used to produce sugar molecules from carbon dioxide through a process called the Calvin Cycle.
The Calvin Cycle produces one molecule of sugar for every six molecules of carbon dioxide.

The terminal acceptor for the electrons during the electron transport chain is oxygen.Photosynthesis and cellular respiration are complementary processes by which living things obtain needed substances. They both consume and create the same substances water, glucose, oxygen, and carbon dioxide but in different ways.
Through these processes, plants obtain the carbon dioxide they need and living organisms obtain the oxygen they need. They are also necessary to the energy exchange that living things need to survive. Photosynthesis is the process by which green plants create their own food by turning light energy into chemical energy.
Chlorophyll in the leaves transform carbon dioxide, water, and minerals into oxygen and glucose. Photosynthesis takes place in the chloroplasts of cells. This process is what gives energy to all living organisms either directly or indirectly. Without it, life on Earth would cease to exist. Cellular respiration, on the other hand, is the process by which living things convert oxygen and glucose to carbon dioxide and water, thereby yielding energy.
It does not require the presence of sunlight and is always occurring in living organisms. Cellular respiration takes place in the mitochondria of cells. While photosynthesis requires energy and produces food, cellular respiration breaks down food and releases energy.
Plants perform both photosynthesis and respiration, while animals can only perform respiration. Toggle navigation. Cellular respiration. Photosynthesis vs. Cellular respiration Photosynthesis and cellular respiration are complementary processes by which living things obtain needed substances.Cellular respiration takes place in the every living organisms, as it is the simple process of converting oxygen and glucose into carbon dioxide and water and ultimately producing energy for the cells of the body.
On the contrary, photosynthesis occurs in green plants, which contain chlorophyll and uses sunlight and water to convert it into energy. These are the two reciprocal process, with the same aim of obtaining energy but by using different methods, different sources and thus giving out different products.
Even both are necessary for the exchange of energy which is required by the living things. Though cellular respiration is performed by all types of the living cell whether a plant or an animal, prokaryotes or eukaryotes but photosynthesis is executed in green plants only and in few bacteria. One cant imagines the work to be performed without the requirement of energy, whether internally or externally, directly or indirectly.
Therefore we can say that these two processes are one of the essential elements of maintaining life on the Earth. At this moment we will consider the difference between the two essential and energy providing reactions to the living cells, where one is cellular respiration and another is photosynthesis. Basis for Comparison Cellular Respiration Photosynthesis Meaning Cellular respiration is the process of converting energy and providing it to the different cells of the body.
Here the glucose and oxygen are converted to carbon dioxide and water, and thus energy ATP is released. The process of using the sunlight and water to convert it into energy is called as photosynthesis, which is specially performed by the green plants and few bacteria.
The green pigment called chlorophyll is responsible for this conversion process. Occurs in The living cell, as well in green and non-green plants. Photosynthesis occurs only in plants containing chlorophyll. Cellular respiration occurs in light day as well as in the dark night. Photosynthesis takes place in light day only.
Reaction involved 1.
Glycolysis which occur in the cell cytoplasm. Krebs or Citric acid cycle occurs in the mitochondrial matrix of the cell. Electron Transport Chain or oxidative phosphorylation which occurs in the mitochondrial membrane. The light reaction which occurs in grana of the chloroplast. Dark reaction or Calvin cycle taking place in the stroma of the chloroplast.
Photolysis or Water-spitting complex which takes place in thylakoid lumen. Energy It is an exothermic reaction, as energy is released during this process. It is an endothermic process, as energy is stored or utilised. The energy which is released is in the form of ATP is used in various metabolic activities. The energy is in the form of glucose or chemical energy, which is used during the dark reaction.
The potential energy is converted into the kinetic energy. Light energy is converted into potential energy. Oxidative phosphorylation In the cellular respiration oxidative phosphorylation occurs. Here photophosphorylation occurs.Learn the differences between cellular respiration and photosynthesis. Photosynthesis is a chemical process that takes place in the presence of light, light energy from the sun is used to produce ATP energy and other molecules known as NADPH.
Photosynthesis occurs in the chlorophyll containing plant cells. Chlorophyll absorbs the light energy and utilizes it to produce carbohydrates from carbon dioxide and water. These carbohydrates produced by the plants as a source of immediate energy for growth, reproduction and absorption of nutrients. Through the process, oxygen is produced and released into the atmosphere.
Cellular respiration is the process of oxidizing food molecules or breaking down chemical bonds of glucose into carbon dioxide and water.
The energy released in the process is trapped in the form of ATP and used by different energy consuming activities of the cell. Photosynthesis takes place in the plant leaves containing the chlorophyll pigment.
Cellular respiration on the other hand, takes place in the cytoplasm and mitochondria of the cell. The main purpose of photosynthesis is to capture and conversion of light energy from the sun into chemical energy and storing it in the bonds of glucose.
On the contrary, the main purpose of cellular respiration is to release the chemical energy stored in form of glucose to produce ATP for the cell. Photosynthesis makes use of sunlight to produce food glucose molecules. Cellular respiration on the other hand, makes use of the glucose molecules to produce energy-storing ATP molecules. Photosynthesis uses water, sunlight and carbon dioxide from the atmosphere to create glucose molecules and release oxygen as a by-product.
Cellular respiration on the other hand, uses glucose molecules and oxygen to produce ATP molecules and carbon dioxide as the by-product. In photosynthesis, the electron transport chain occurs at the beginning of the process, however, in cellular respiration, the electron transport chain occurs at the end of the process. Photosynthesis occurs only in plants, algae and some bacteria whereas cellular respiration takes place in all types of living organisms.
Difference Between Cellular Respiration and Photosynthesis
Photosynthesis involves conversion of one type of energy into another that is light energy into chemical energy while cellular respiration involves using that chemical energy and breaking it down to release energy. Photosynthesis happens only when there is sunlight whereas cellular respiration occurs at all times, it does not depend on sunlight for it to happen. Photosynthesis takes place in two stages; the stages include the light dependent reaction light cycle and light independent reaction Calvin cycle.
