Plants release oxygen which is a by-product of photosynthesis, and we breathe in oxygen so that our cells can carry out cellular respiration and generate ATP. Show
Respiration and photosynthesis are biological reactions in the environment that complement each other. Both are similar reactions that occur in a specific manner. In the process of respiration, oxygen and glucose yield water and carbon dioxide, while carbon dioxide and water yield glucose and oxygen during the process of photosynthesis. Both cellular respiration and photosynthesis are parts of a mutually beneficial relationship. Photosynthesis cannot occur without cellular respiration and cellular respiration certainly cannot occur without photosynthesis. Photosynthesis and cellular respiration are in many respects the “reverse” of one another. Photosynthesis is an anabolic process, whereas cellular respiration is a catabolic process. Let us explore more differences between cellular respiration and photosynthesis

It is important to understand the differences between the two. Photosynthesis and cellular respiration are the life processes performed by most living organisms to obtain usable energy from nature. While photosynthesis is performed by most plants which can prepare their own food, most animals fulfill their energy requirements through cellular respiration. Photosynthesis is the process by which plant cells convert light energy from the sun into chemical energy, so as to create energy-rich carbohydrate molecules like glucose. Cellular respiration is the process of breaking down food molecules to obtain energy and store it in the form of adenosine triphosphate (ATP) molecules. Plant cells, after creating sugar molecules through photosynthesis, undergo cellular respiration to create ATP molecules. Animals obtain food molecules from plants and other organisms, and then undergo cellular respiration to obtain ATP molecules. All living organisms utilize these stored ATP molecules to carry out their metabolic processes. PhotosynthesisPhotosynthesis takes place in the cells of plant leaves. It occurs in structures called chloroplasts, which contain chlorophyll. The plant cells absorb light from the sun through the pigment chlorophyll, and using water and carbon dioxide obtained from the environment. They undergo a series of chemical reactions to produce carbohydrate molecules. Chemical reaction in PhotosynthesisCarbon Dioxide + Water + Sunlight → Glucose + Oxygen Stages in the Process of PhotosynthesisLight-dependent ReactionsThis is the first stage of the photosynthetic process. These reactions take place in the presence of sunlight, and use light energy from the sun to produce ATP molecules and other molecules known as NADPH. These molecules are used as the energy source to carry out the chemical changes in the next stage of photosynthesis. Light-independent Reactions (Calvin Cycle)In this stage of photosynthesis, energy-containing sugar molecules are synthesized. The ATP and NADPH produced are used to fuel the reactions in this stage. Here, CO2 molecules are broken down and converted into sugars and other compounds. The Calvin Cycle is repeated twice in order to yield one molecule of glucose. Cellular RespirationCellular respiration takes place in the same way in both plants and animals. Living cells obtain the products of photosynthesis (sugar molecules) and undergo cellular respiration to produce ATP molecules. Some cells respire aerobically, using oxygen, while others undergo anaerobic respiration, without using oxygen. The process involves a set of chemical reactions to convert chemical energy from the glucose molecules into ATP molecules. Chemical reaction in Cellular RespirationGlucose + Oxygen → Carbon dioxide + Water + Energy (ATP) Stages in the Process of Cellular RespirationGlycolysisCellular respiration begins at this stage in the cytoplasm of the cells, and yields 2 carbon-based molecules called pyruvate, and 2 molecules of ATP. Oxygen plays no part during this stage, so it is called anaerobic respiration. Aerobic RespirationThis process takes place in specialized structures within the cell called mitochondria, and uses the products of glycolysis, the pyruvate molecules, to release energy, along with CO2 and water as the by-products of the reaction. The energy released is stored in the form of ATP molecules. Usually, a total of 38 ATP molecules is produced. Differences between Photosynthesis and Cellular Respiration
What is the relationship between photosynthesis and cellular respiration in plants?Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.
What is the relationship between the photosynthesis and cellular respiration equation?The products of one process are the reactants of the other. Notice that the equation for cellular respiration is the direct opposite of photosynthesis: Cellular Respiration: C6H12O6 + 6O2 → 6CO2 + 6H2O. Photosynthesis: 6CO2 + 6H2O → C6H12O6+ 6O.
What is the relationship between cellular respiration and photosynthesis quizlet?What is the relationship between photosynthesis and cellular respiration? Photosynthesis removes carbon dioxide from the atmosphere, and cellular respiration puts it back. Photosynthesis releases oxygen into the atmosphere, and cellular respiration uses that oxygen to release energy from food.
