Detailed explanation-1: -The process of breakdown of food in the cell with the release of energy is called cellular respiration. Cellular respiration takes place in the cells of all organisms. In the cell, the food (glucose) is broken down into carbon dioxide and water using oxygen.
Detailed explanation-2: -Respiration releases energy-it is an exothermic process. The energy is stored in molecules of ATP . ATP can be broken down in other processes in cells to release the stored energy. Don’t confuse respiration with photosynthesis.
Detailed explanation-3: -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.
