When you go through the concepts of cellular respiration and photosynthesis, you are bound to find some striking similarities. Nonetheless, fundamentally they are quite different from one another. Before we head straight to the differences between respiration and photosynthesis, let’s become familiar with the concepts. In turn, it will help to differentiate the two more effectively. What is Photosynthesis?It occurs only in cells that have chlorophyll and can only take place in the presence of sunlight. The said process uses water and carbon dioxide and produces oxygen and carbohydrates as by-products. It is noteworthy that light energy is changed into chemical energy during photosynthesis. Also, hydrogen released through photolysis is absorbed by NADP, which in turn gets reduced into NADPH2. It is expressed as 6CO2 + 6H2O \[\longrightarrow\] C6H12O6 + 6O2 Hence, Calvin Cycle forms an integral part of photosynthesis. What is Cellular Respiration?Essentially, it is an ongoing catabolic process. The process uses carbohydrates and oxygen and releases water and carbon dioxide as end products. Notably, on oxidation, the energy released through carbohydrates and other vital substrates gets absorbed in ATP. Nevertheless, a fraction of energy is lost as heat amidst the process. Furthermore, during the simultaneous process of oxidative phosphorylation, ATP molecules are produced from the oxidation of carbohydrates. Subsequently, synthesized ATP is used during various stages of the metabolic process. Additionally, glycolysis and oxidation of pyruvic acid take place during cellular respiration. It is expressed as C6H12O6 + 6O2 \[\longrightarrow\] 6CO2 + 6H2O Are you still wondering - “How are photosynthesis and cellular respiration different?” Check below to know more. Differences between Photosynthesis and RespirationIt must be noted that despite being a similar process, photosynthesis and respiration takes place in reverse. For instance, in photosynthesis, the input, namely, water and carbon dioxide, generates glucose and oxygen as by-products. On the other hand, in cellular respiration, oxygen and Glucose release water and carbon dioxide as by-products. Also, in photosynthesis, the sun’s light energy is first converted into chemical energy and is then stored in glucose bonds. Conversely, in cellular respiration, the chemical energy in Glucose is released to yield ATP. Likewise, both follow a different metabolic process. For instance, photosynthesis follows an anabolic process. In the metabolic process, the carbon dioxide and energy produced from NADPH and ATP are utilized to create Glucose molecules. Similarly, cellular respirations follow a catabolic process. Glucose is broken down for the production of ATP, FADH2, NADH, and carbon dioxide. Look at the table below to check out the fundamental difference between photosynthesis and respiration in a nutshell.
DIY:What are photosynthesis and cellular respiration? Explain in your own words. Similarities between Photosynthesis and RespirationDespite the difference between photosynthesis and respiration, both processes are interdependent. Let’s take a quick look at the comparison between photosynthesis and respiration from the figure below. It also answers the query of – “What is the difference between respiration and photosynthesis?” in brief. ConclusionThis is all about the meaning, explanation, and difference between photosynthesis and respiration. Learn how both biological processes are different from each other in different aspects. Concentrate on the features of these biochemical processes to understand the differences perfectly. Want to read offline? download full PDF here Download full PDF Is this page helpful?  Recently Updated Pages Recently Updated Pages What are the differences between photosynthesis and cellular respiration?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 are the differences and similarities between photosynthesis and cellular respiration?Both are processes within the cell which make chemical energy available for life. Photosynthesis transforms light energy into chemical energy stored in glucose, and cellular respiration releases the energy from glucose to build ATP, which does the work of life.
How is photosynthesis different than cellular respiration quizlet?Photosynthesis uses carbon dioxide and water, produces glucose and oxygen, and takes place in chloroplasts. Cellular respiration uses glucose and oxygen, produces carbon dioxide, water, and ATP, takes place in mitochondria.
