This creates a sugar chain and six units of oxygen. What is the Cellular Respiration and Photosynthesis Equation? 6NADH, 2FADH2 and 2ATPs per one glucose molecule are produced by the Krebs cycle. The living cell, as well in green and non-green plants. This organic compounds can be used by cells as food. Equation of Photosynthesis is C6H12O6 + 6O2 ~> 6CO2 + 6H2O and equation of Respiration is 6CO2 + 6H2O ~> C6H12O6 + 6O2. Photosynthetic organisms contain special pigments like chlorophyll and carotenoids in order to trap the light. Anaerobic respiration occurs in hydrothermal vents in the deep sea. In contrast, cellular respiration occurs in all living forms on earth. Cellular Respiration vs Photosynthesis. Photosynthesis and cellular respiration are the main two metabolic processes that occur in organisms, driving all the cellular processes in the body. 4. Reference:Cooper, Geoffrey M. “Photosynthesis.” The Cell: A Molecular Approach. While photosynthesis requires energy and produces food, cellular respiration breaks down food and releases energy. Cellular Respiration: Cellular respiration is the process which converts the biochemical energy into energy in ATP, eliminating carbon dioxide and water as waste products. During respiration, food is oxidized in order to obtain the potential energy stored in the form of ATP. Cellular respiration is the process which converts the biochemical energy into energy in ATP, eliminating carbon dioxide and water as waste products. To do this, the chloroplasts will combine units of carbon dioxide into chains of 6 carbons, 12 hydrogens, and 6 oxygens. A "difference between" reference site. Photosynthesis takes place in two stages of the light reactions and the dark reactions. During photosynthesis, carbon dioxide and water are used in the synthesis of organic compounds with the aid of sunlight. 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 … Only two ATPs are produced per glucose molecule in fermentation. The process of photosynthesis is shown in figure 2. Cellular respiration is the process of converting energy and providing it to the different cells of the body. In the cellular respiration oxidative phosphorylation occurs. During cellular respiration, energy in the form of ATP is produced by breaking down food. The citric acid cycle is the second stage of cellular respiration, which is also called Krebs cycle. Therefore, the main difference between photosynthesis and cellular respiration is their contribution in the metabolism of a cell. The light reaction which occurs in grana of the chloroplast. Light energy is converted into potential energy. 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. 5. The first stage of photosynthesis is the light reaction. Cellular respiration takes place in all living organisms in mitochondria, whereas photosynthesis occurs only in plants containing chlorophyll. Cellular Respiration: Energy is liberated during cellular respiration. also read the difference between virus and bacteria. Berg, Jeremy M. “The Citric Acid Cycle.” Biochemistry. 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. The energy is in the form of glucose or chemical energy, which is used during the dark reaction. 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: During photosynthesis, light energy is converted into potential energy. 2017. Cellular Respiration: Pigments are not involved in cellular respiration. It takes place in all the living cells of plant. Energy is the basic source an individual needs for the survival of life. Other than glucose, 18 ATP and 12 NADPH are produced during the Calvin cycle. Dark reaction occurs in the stroma. Some differences between photosynthesis and respiration are that photosynthesis only happens in sunlight while respiration happens constantly … 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. Photosynthesis and cellular respiration are in many respects the “reverse” of one another. Lactic acid fermentation in muscle cells and ethanol fermentation in yeast are the two types of fermentation found among organisms. Pigments like chlorophyll, carotenoids and phycobilins are used to trap the light energy. The electron donor in oxygenic photosynthesis is water whereas the electron donor in anoxygenic photosynthesis is a variant like hydrogen sulfide rather than water. Cellular Respiration: Cellular respiration is a catabolic process, which degrades organic compounds. Photosynthesis: Energy is stored during photosynthesis. Cellular Respiration: Carbohydrates are used during cellular respiration. Plants perform both photosynthesis and respiration, while animals can only perform respiration. This is glucose, which can then be modified and combined with other glucose molecules to be stored as starches and complex sugars like fructose. Cellular Respiration: Energy is liberated in the form of ATP, which can be utilized by other cellular processes. In eukaryotes, cellular respiration occurs in specialized organelles called mitochondria. Aerobic respiration and anaerobic respiration are the two types of respiration found on earth. 03 Apr. During Krebs cycle, carbon dioxide is eliminated as a waste, while reducing NAD into NADH. 2nd edition. “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. ATP is the main purpose for cellular respirationwhereas for photosynthesis, ATP is only needed in order to create glucose. 1. “Photosynthesis Images” By Masroor.nida.ns – Own work (CC BY-SA 4.0) via Commons Wikimedia2. Main Difference. What is the difference between Photosynthesis and Cellular Respiration. 3. Web. What is Photosynthesis       – Definition, Characteristics, Types, Process 2. The process of cellular respiration is shown in figure 4. Photosynthesis: Carbon dioxide and water are utilized and oxygen is released during photosynthesis. The generating high energy electrons are transferred into the third protein complex, cytochrome bf complex. In aerobic respiration, the oxidizing agent or the final electron acceptor is molecular oxygen. Therefore, during photosynthesis, light energy is converted into potential chemical energy. Another difference between photosynthesis and cellular respiration is that the first is an endothermic reaction, while the second is exothermic. Photosynthesis is an anabolic process, whereas cellular respiration is a catabolic process. Stored food like carbohydrates, fats and proteins in organisms are used in the form of glucose by cellular respiration. The chloroplast uses the energy harnessed from these photons and their interaction with the cytochromes and other proteins to drive the formation of glucose. Privacy. Photosynthesis: Photosynthesis only occurs in light. 2017. Cooper, Geoffrey M. “Metabolic Energy.” The Cell: A Molecular Approach. ADVERTISEMENTS: The upcoming discussion will update you about the differences between respiration and photosynthesis. Carbon dioxide and water is produced as waste during cellular respiration. Photosynthesis: Carbohydrates are synthesized during photosynthesis. It is an exothermic reaction, as energy is released during this process. ADVERTISEMENTS: 3. Photosynthesis: Photosynthesis occurs in thylakoid membrane and stroma of chloroplasts in plants. 2nd edition. Hence in photosynthesis you have the light dependent reactions and the dark reactions while in respiration there is aerobic respiration and anaerobic respiration. Photosynthesis occurs only in plants containing chlorophyll. 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.

Photosynthesis only occurs in chlorophyllous organisms. It is an endothermic process, as energy is stored or utilised. Two pyruvate molecules are then imported into mitochondria. Home » Science » Biology » Cell Biology » Difference Between Photosynthesis and Cellular Respiration. Photosynthesis: Photosynthesis is found only in chlorophyllous cells. 1. 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. In 3-5 sentences, argue which one of these two processes is used at certain times of day by plants. Web. The relationship between photosynthesis and cellular respiration is such that the products of one system are the reactants of the other. The differences between photosynthesis vs. cellular respiration include the stages and processes involved, reactants, cell organelles, and chemical reactions. Key differences between Photosynthesis and Cellular Respiration Photosynthesis releases oxygen and other organic compounds, while cellular respiration releases carbon dioxide and water. Cellular Respiration: Oxygen is utilized and carbon dioxide and water are released during cellular respiration. Photosynthesis used two electron transport chains while cellular respiration uses one electron transport chain. On the contrary, photosynthesis occurs in green plants, which contain chlorophyll and uses sunlight and water to convert it into energy. The first stage of cellular respiration is the glycolysis. “Photosynthesis” By Cykl_Calvina.svg: PisumThylakoid_membrane.svg: YikrazuulThylakoide.png: Tameeria pour la version anglaise, Pascal Corpet pour la traductionderivative work: Marek M (talk) – Cykl_Calvina.svgThylakoid_membrane.svgThylakoide.png (CC BY-SA 3.0) via Commons Wikimedia3. Photosynthesis occurs in the leaves of plants with li… 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. G-3-P is formed in both processes-In Glycolysis (cell respiration) and in Calvin cycle (photosynthesis). While one is a forward event that seeks to capture, the other is a backward process that seeks to release. The […] The principal difference, however, between photosynthesis and respiration is that photosynthesis utilizes carbon dioxide and water in the presence of … Cellular Respiration: Cellular respiration occurs in both light and dark. The process where energy is produced for the cell to do work is known as. Photosynthesis: Photosynthesis is the production of glucose from carbon dioxide and water by obtaining energy from sunlight. Photosynthesis cannot occur without cellular respiration and cellular respiration certainly cannot occur without the photosynthesis. One method of how animals derive this energy is through the process of cellular respiration. Cellular Respiration: Glycolysis, Citric acid cycle and electron transport chain are the three steps in cellular respiration. Respiration and Photosynthesis are two of the processes, which revolve around the concepts of storage of energy and release of energy. Difference Between Cellular Respiration and Photosynthesis. Oxygen gas is a by-product of photosynthesis. In the presence of oxygen, pyruvate combines with oxaloacetate (C4) in order to form citrate (C6), eliminating acetyl-CoA during the citric acid cycle. All living things require a constant supply of energy in order to survive. Cellular respiration takes place in the mitochondria of cells. The chemical reaction of cellular respiration is shown below. Difference Between Photosynthesis and Cellular Respiration: Conclusion. Dark reaction is also called the Calvin cycle. 1. These are the two reciprocal process, with the same aim of obtaining energy but by using different … Glycolysis which occur in the cell cytoplasm. Oxygenic photosynthesis and anoxygenic photosynthesis are the two types of photosynthesis found on earth. Photosynthesis: Dry weight of the plant is increased during photosynthesis. Photosynthesis occurs in two stages such as light stage and dark stage while cell respiration occurs in four stages as Glycolysis, Pyruvate Oxidation, Krebs cycle, and Electron Transport Chain. To conclude this post, it is evident that this photosynthesis vs cellular respiration comparison shows how these two contradict each other with the same results. In plants, photosynthesis occurs in specialized plastids called chloroplasts that are found in the cytoplasm of photosynthetic cells. The energy which is released is in the form of ATP is used in various metabolic activities. Difference Between Photosynthesis and Cellular Respiration Main Difference. Chlorophyll is green because the light required for photosynthesis is red and blue light, leaving green light to be reflected back to our eyes. This process is occurring during cellular respiration and photosynthesis. During glycolysis, glucose (C6) is broken down into two pyruvate (C3) molecules in the cytoplasm. Oxygen gas is liberated during photosynthesis, which can be used in cellular respiration. Photosynthesis: Photosynthesis is an anabolic process, which synthesizes complex organic compounds. What is the difference between Photosynthesis and Cellular Respiration. Cellular respiration takes place in mitochondria while photosynthesis in the chloroplast of green plants. Utilizes oxygen and carbohydrates. In other words, we can say that they are the similar sort of reactions occurring in reverse.
