However, photosynthesis stores the energy of sunlight in the form of chemical energy in sugar and starch molecules while cellular respiration breaks down organic compounds such as sugar and starch in order to produce energy in the form of ATP (energy currency). Dr.Samanthi Udayangani holds a B.Sc. 1. 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. It takes place in all the living cells of plant. @media (max-width: 1171px) { .sidead300 { margin-left: -20px; } } Flashcards. The reactants for cellular respiration are … Furthermore, both processes depend on each other. Chemiosmotic Theory states that Electron transport and ATP synthesis are coupled by a proton gradient across the inner mitochondrial membrane. Photosynthesis is the food making process or energy storage process, whereas respiration is the … Photosynthesis is a metabolic pathway that converts mild power into chemical power.cellular respiration is the set of the metabolic reactions and approaches that ensue in organisms' cells to transform biochemical power from food into adenosine triphosphate (ATP), and then launch waste products preliminary substrates of photosynthesis are carbon dioxide and water; the flexibility … STUDY. To do this, the chloroplasts will combine units of carbon dioxide into chains of 6 carbons, 12 hydrogens, and 6 oxygens. Photoautotrophs produce their own food by this process. 3. 2. in Molecular and Applied Microbiology, and PhD in Applied Microbiology. In photosynthesis, the reaction only takes place in the presence of chlorophyll while cellular respiration is independent of the catalyst for respiration reaction. 1. Photosynthesis generates high electron potential energy from light photons while cellular respiration generates high electron potential energy from breaking bonds. Thus, this concludes the summary of the difference between photosynthesis and cellular respiration. 4. The chloroplast uses the energy harnessed from these photons and their interaction with the cytochromes and other proteins to drive the formation of glucose. Photosynthesis vs. Cellular respiration - - Photosynthesis and cellular respiration are complementary processes by which living things obtain needed substances. It can only occur in plants, algae, and very few bacteria. The differences between photosynthesis vs. cellular respiration include the stages and processes involved, reactants, cell organelles, and chemical reactions. ADVERTISEMENTS: 3. The overall process of cellular respiration takes occurs in the mitochondria of cells. Photosynthesis is an anabolic process that ends in the production of carbohydrate molecules. These organisms are also called as photoautotrophs. It is said to be the main process in which a cell of living organisms emits chemical energy to fuel cellular activity. Photosynthesis converts the light energy of the sun into chemical energy of sugar by releasing oxygen as a byproduct. Light reaction needs the photons and water to give out oxygen leading to the production of ATP and NADPH. Cellular respiration is different from the photosynthesis on many grounds in which the major difference is that it don’t require the need of sunlight at all and is always occurring in all living organisms either animals or plants. The overall process of cellular respiration takes occurs in the mitochondria of cells. Oxygen is the water product or output that is released in most of the photosynthesis processes. In fact it could be said that in both cases it is the same process, but in the opposite direction. “Photosynthesis en” By At09kg: originalWattcle : vector graphics – This file was derived from Photosynthesis.gif (CC BY-SA 4.0) via Commons Wikimedia During photosynthesis process, oxygen is released and carbon dioxide while in cellular respiration, carbon dioxide is released, and oxygen is absorbed. Plants perform both photosynthesis and respiration, while animals can only perform respiration. In photosynthesis, energy is provided by photons while in cellular respiration, energy in provided by the catabolic processes. Some differences between photosynthesis and respiration are that photosynthesis only happens in sunlight while respiration happens constantly … Photosynthesis vs. Cellular Respiration. 6CO2 + 12H2O + light –> C6H12O6 + 6O2 + 6H20, Occurs in algae, plants and some bacteria, Occurs in all living organisms either plants or animals. 10 Difference between Cellular Respiration and Photosynthesis Respiration is a complex process which includes absorption of oxygen, conversion of complex substance like carbohydrates to carbon dioxide and water with release of energy as ATP to drive all cellular activities and as a … The former takes place in four different stages – glycolysis, linking, Kreb’s cycle, and electron transport chain levels. Log in Sign up. Photosynthesis involves the use of energy from sunlight, water and carbon dioxide to produce glucose and oxygen. Her research interests include Bio-fertilizers, Plant-Microbe Interactions, Molecular Microbiology, Soil Fungi, and Fungal Ecology. Prokaryotic cells carry out cellular respiration in the cytoplasm whereas eukaryotic cells carry out cellular respiration mostly inside the mitochondria of the cell. What are the differences between Cellular Respiration and Photosynthesis? Similarities between Cellular Respiration and Photosythesis. The main difference between photosynthesis and cellular respiration is that during the process of photosynthesis energy is stored while energy released in cellular respiration. The key difference between respiration and photosynthesis is that respiration burns food and produces energy while photosynthesis produces foods by capturing the sunlight. The inputs in the photosynthesis are water and carbon dioxide while inputs in the case of cellular respiration are oxygen and glucose. Photosynthesis and cell respiration are in many respects the reverse of one another. Photosynthesis is a process that converts light energy into chemical energy of carbohydrates in the presence of sunlight and chlorophylls. In photosynthesis, the provision of vitality whereas in cellular respiration, chemical bonds are the provision of vitality. Browse. Photosynthesis is an anabolic process, whereas cell respiration is a catabolic process; Photosynthesis: Water is broken down to oxygen to release electrons for an electron transport chain amazing thankyou!! Photosynthesis is an anabolic process, whereas cellular respiration is a catabolic process. Core Difference between Cellular Respiration and Photosynthesis. Most other living organisms depend on these carbohydrates produced by plants through photosynthesis. All living organisms carry out respiration: aerobic respiration in the presences of oxygen, and anaerobic respiration in the absence of oxygen. ADVERTISEMENTS: The upcoming discussion will update you about the differences between respiration and photosynthesis. Plant, algae, and cyanobacteria are the main groups of photoautotrophs. Upgrade to remove ads. The main difference between photosynthesis and cellular respiration is that photosynthesis is an anabolic process, where the synthesis of organic compounds occurs, storing energy whereas cellular respiration is a catabolic process, where the stored organic compounds are utilized, producing energy. Photosynthesis involves the production of NADPH while cellular respiration involves the production of both FADH and NADH. Photosynthesis and cellular respiration are vital processes of living organisms. Differences. The biggest difference between photosynthesis and respiration is that photosynthesis only occurs in plants and some bacteria while respiration occurs in all living organisms. 2. Photosynthesis happens only in those cells containing chlorophyll while cellular respiration happens in all cells and it is independent of chlorophyll. In the absence of one, the chances of survival for the other drastically degrade. Photosynthesis can be divided into two main processes: light dependent (light reaction) process and light independent (dark reaction) process. 1. Different species perform the photosynthesis process in a variety of ways. In aerobic respiration, one glucose molecule can generate 36-38 molecules of ATP, but in anaerobic respiration (through glycolysis and fermentation) only 2 ATP molecules could be derived. Despite the differences between these two processes, there are some similarities. Photosynthesis takes place in two stages of the light reactions and the dark reactions. Moreover, cellular respiration can be divided into three metabolic processes as glycolysis, Krebs cycle and electron transport chain. Hence in photosynthesis you have the light dependent reactions and the dark reactions while in respiration there is aerobic respiration and anaerobic respiration.
