Detailed explanation-1: -Overview. Cellular respiration is the process by which the energy in food is converted into energy that can be used by the body’s cells. The energy stored in glucose is transferred to ATP. The process can be summarized as: glucose + oxygen carbon dioxide + water.
Detailed explanation-2: -During glycolysis, a glucose molecule with six carbon atoms is converted into two molecules of pyruvate, each of which contains three carbon atoms. For each molecule of glucose, two molecules of ATP are hydrolyzed to provide energy to drive the early steps, but four molecules of ATP are produced in the later steps.
Detailed explanation-3: -Respiration. The chemical process of breaking down glucose and releasing energy for carrying out life processes is called Respiration.
