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: -Through the process of cellular respiration, the energy in food is converted into energy that can be used by the body’s cells. During cellular respiration, glucose and oxygen are converted into carbon dioxide and water, and the energy is transferred to ATP.

Detailed explanation-3: -During cellular respiration, a glucose molecule is gradually broken down into carbon dioxide and water. Along the way, some ATP is produced directly in the reactions that transform glucose. Much more ATP, however, is produced later in a process called oxidative phosphorylation.

Detailed explanation-4: -4.10 Summary. Cellular respiration is the aerobic process by which living cells break down glucose molecules, release energy, and form molecules of ATP .

Detailed explanation-5: -2) Breaking down the food molecules releases the energy that was holding them together, and that released energy is temporarily stored by the cell for the re-building process.
