Detailed explanation-1: -Because the energy to drive ATP synthesis in mitochondria ultimately derives from the oxidative breakdown of food molecules, the phosphorylation of ADP to form ATP that is driven by electron transport in the mitochondrion is known as oxidative phosphorylation.

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: -ATP consists of an adenosine molecule bonded to three phosphate groups in a row. During cellular respiration, energy in food is converted into chemical energy that can be used by cells. This chemical energy is stored in the pyrophosphate bond, which lies between the last two phosphate groups of ATP.

Detailed explanation-4: -When the cell has extra energy (gained from breaking down food that has been consumed or, in the case of plants, made via photosynthesis), it stores that energy by reattaching a free phosphate molecule to ADP, turning it back into ATP. The ATP molecule is just like a rechargeable battery.

Detailed explanation-5: -These bonds are constantly being made and broken. Energy from food is converted into energy stored in ATP. And that’s how your cells have the power to continue working to maintain your health.
