Biology: Photosynthesis: Cellular Respiration by ClassOf1

VIEWS: 488 PAGES: 5

Photosynthesis and cellular respiration are two important metabolic processes. This is a question where both the process are compared and contrasted between each other among the reactants, products, ATP produced, organelles involved etc.

              Question:
              Cellular Respiration and Photosynthesis co-exist as paired metabolic processes.

         ClassOf1 provides expert guidance to College, Graduate, and High school students on homework and assignment problems in
                       Math, Sciences, Finance, Marketing, Statistics, Economics, Engineering, and many other subjects.

              Photosynthesis uses light energy to convert carbon dioxide into glucose, a simple sugar, in two
              steps, the light dependent and light independent reactions. Oxygen is produced as a by product
              during photosynthesis. This reaction stores energy in the chemical bonds of glucose.

              Sugar and other carbohydrates are used as fuel sources by cells. During the process of Aerobic
              Cellular Respiration, glucose is broken down using oxygen. This reaction releases energy which
              is used to create ATP molecules, the energy carrier molecule of cells. The process also releases
              Carbon Dioxide as a byproduct.
