Detailed explanation-1: -What is Respiration? Respiration is a metabolic process that occurs in all organisms. It is a biochemical process that occurs within the cells of organisms. In this process, the energy (ATP-Adenosine triphosphate) is produced by the breakdown of glucose which is further used by cells to perform various functions.
Detailed explanation-2: -During respiration, there is a release of carbon-dioxide and water when glucose is broken down in the presence of oxygen. During this reaction, the energy is released. This energy is stored in the form of ATP.
Detailed explanation-3: -Cellular respiration is a series of chemical reactions that break down glucose to produce ATP, which may be used as energy to power many reactions throughout the body. There are three main steps of cellular respiration: glycolysis, the citric acid cycle, and oxidative phosphorylation.
