difference between photosynthesis and cellular respiration

Please update your bookmarks accordingly. The light is absorbed by photosystem I and II, which are the two protein complexes found in thylakoid membrane, and the absorbed light is transferred to photocenters. This creates a sugar chain and six units of oxygen. Photosynthesis: During photosynthesis, light energy is converted into potential energy. While one is a forward event that seeks to capture, the other is a backward process that seeks to release. Also, in order for cellular respiration to occur, the presence of catalysts is not necessary; as it happens in the case of photosynthesis where the reaction only occurs in the presence of chlorophyll. Hence in photosynthesis you have the light dependent reactions and the dark reactions while in respiration there is aerobic respiration and anaerobic respiration. Oxidative phosphorylation, which is the third stage of cellular respiration occurs in the mitochondrial cristae by the enzyme ATP synthase, producing 30ATPs. Cellular Respiration: Cellular respiration is the process which converts the biochemical energy into energy in ATP, eliminating carbon dioxide and water as waste products. Cellular respiration takes place in mitochondria while photosynthesis in the chloroplast of green plants. Lactic acid fermentation in muscle cells and ethanol fermentation in yeast are the two types of fermentation found among organisms. The first stage of cellular respiration is the glycolysis. Photosynthesis and cellular respiration are the main two metabolic processes that occur in organisms, driving all the cellular processes in the body. This is glucose, which can then be modified and combined with other glucose molecules to be stored as starches and complex sugars like fructose. Examining Photosynthesis and Cellular Respiration Introduction- In Lab 4, the purpose was to examine the process of photosynthesis and cellular respiration and understand the correlation between … 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 … Oxygen and carbohydrates are absorbed in the process. It has the highest contribution in producing food for all the living forms on earth. Also, in photosynthesis, the sun’s light energy is first converted into chemical energy and is then stored in glucose bonds. Therefore, the main difference between photosynthesis and cellular respiration is their contribution in the metabolism of a cell.

One method of how animals derive this energy is through the process of cellular respiration. 2. Photosynthesis: Dry weight of the plant is increased during photosynthesis. Dark reaction occurs in the stroma. 1. On the contrary, photosynthesis occurs in green plants, which contain chlorophyll and uses sunlight and water to convert it into energy. What is Photosynthesis       – Definition, Characteristics, Types, Process 2. During respiration, food is oxidized in order to obtain the potential energy stored in the form of ATP. G-3-P is formed in both processes-In Glycolysis (cell respiration) and in Calvin cycle (photosynthesis). 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. Difference Between Photosynthesis and Cellular Respiration Main Difference. U.S. National Library of Medicine, 01 Jan. 1970. Therefore, during photosynthesis, light energy is converted into potential chemical energy. Photosynthetic organisms contain special pigments like chlorophyll and carotenoids in order to trap the light. ADVERTISEMENTS: The upcoming discussion will update you about the differences between respiration and photosynthesis. The energy is in the form of glucose or chemical energy, which is used during the dark reaction. The high energy electrons in PSI is transferred into a series of ferrodoxin carriers and ultimately, these electrons are transferred into NADP+ by NADPH reductase enzyme, forming NADP. During anaerobic respiration, the final electron acceptor is either inorganic sulfates or nitrates. Photosynthesis occurs only in plants containing chlorophyll. In prokaryotes, it occurs in the cytoplasm itself. Dark reaction is also called the Calvin cycle. Utilizes oxygen and carbohydrates. 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. Definition. 3. Photosynthesis: Photosynthesis is found only in chlorophyllous cells. In plants, photosynthesis occurs in specialized plastids called chloroplasts that are found in the cytoplasm of photosynthetic cells. Cellular Respiration: Cellular respiration occurs in the matrix and the inner membrane of mitochondria and cytoplasm in eukaryotes. Reference:Cooper, Geoffrey M. “Photosynthesis.” The Cell: A Molecular Approach. In aerobic respiration, the oxidizing agent or the final electron acceptor is molecular oxygen. Cellular Respiration: Oxidative phosphorylation occurs during cellular respiration. The 18 ATPs are used by the Calvin cycle itself. In eukaryotes, cellular respiration occurs in specialized organelles called mitochondria. The light reaction which occurs in grana of the chloroplast. Photosynthesis: Photosynthesis is found only in chlorophyllous cells. Cellular respiration takes place in the mitochondria of cells. Some differences between photosynthesis and respiration are that photosynthesis only happens in sunlight while respiration happens constantly … “CellRespiration”By RegisFrey – Own work (CC BY-SA 3.0) via Commons Wikimedia, Lakna, a graduate in Molecular Biology & Biochemistry, is a Molecular Biologist and has a broad and keen interest in the discovery of nature related things, Difference Between Photosynthesis and Cellular Respiration, 3. Cellular Respiration: During cellular respiration, potential energy is converted into kinetic energy. What is the relationship between photosynthesis and cellular respiration?Photosynthesis and cellular respiration are opposite equations. Photosynthesis is an anabolic process, whereas cellular respiration is a catabolic process. Photosynthesis and cellular respiration are two basic metabolic processes occurring in the energy conversion of ecosystems. Cellular Respiration: Pigments are not involved in cellular respiration. Difference Between Cellular Respiration and Photosynthesis. Cellular Respiration: Cellular respiration is a catabolic process, which degrades organic compounds. Carbon dioxide and water is produced as waste during cellular respiration. 1. This organic compounds can be used by cells as food. Glycolysis which occur in the cell cytoplasm. Aerobic respiration and anaerobic respiration are the two types of respiration found on earth. Respiration: 1. The second stage of photosynthesis is the dark reaction, where the NADPH and ATP produced in light reaction are used as the energy sources to synthesize glucose. Cellular respiration involves aerobic (glycolysis) and anaerobic respiration. Photosynthesis: Photosynthesis is the production of glucose from carbon dioxide and water by obtaining energy from sunlight. Let us explore more differences between cellular respiration and photosynthesis Chemiosmotic Theory states that Electron transport and ATP synthesis are coupled by a proton gradient across the inner mitochondrial membrane. Photosynthesis cannot occur without cellular respiration and cellular respiration certainly cannot occur without the photosynthesis. Cellular respiration occurs in light (day) as well as in the dark (night). The chemical reactions of both oxygenic and anoxygenic photosynthesis are shown below. All living things require a constant supply of energy in order to survive. Cellular respiration is the process which converts the biochemical energy into energy in ATP, eliminating carbon dioxide and water as waste products. Difference Between Photosynthesis and Cellular Respiration: Conclusion. Berg, Jeremy M. “The Citric Acid Cycle.” Biochemistry. Processes in photosynthesis are divided on basis of requirement of sunlight while respiration processes are divided on basis of requirement of oxygen. This process occurs in the chloroplasts, using chlorophyll. What is Cellular Respiration      – Definition, Characteristics, Types, Process 3. In contrast, cellular respiration occurs in all living forms on earth. Anaerobic respiration occurs in hydrothermal vents in the deep sea. The first stage of photosynthesis is the light reaction. Photosynthesis is the production of glucose from carbon dioxide and water by obtaining energy from sunlight. Main Difference. Photosynthesis used two electron transport chains while cellular respiration uses one electron transport chain. Photosynthesis and cellular respiration are in many respects the “reverse” of one another. Web. Start studying Differences Between Photosynthesis and Cellular Respiration. This catabolic process continues throughout the day and night. The chemical formula for the process requires six molecules of carbon dioxide and six molecules of water plus the energy from light. In the cellular respiration oxidative phosphorylation occurs. The process where energy is produced for the cell to do work is known as. Equation of Photosynthesis is C6H12O6 + 6O2 ~> 6CO2 + 6H2O and equation of Respiration is 6CO2 + 6H2O ~> C6H12O6 + 6O2. Chlorophyll is green because the light required for photosynthesis is red and blue light, leaving green light to be reflected back to our eyes. Oxygen gas is liberated during photosynthesis, which can be used in cellular respiration. Learn vocabulary, terms, and more with flashcards, games, and other study tools.
