Detailed explanation-1: -ATP is consumed for energy in processes including ion transport, muscle contraction, nerve impulse propagation, substrate phosphorylation, and chemical synthesis. These processes, as well as others, create a high demand for ATP.

Detailed explanation-2: -ATP is able to power cellular processes by transferring a phosphate group to another molecule (a process called phosphorylation). This transfer is carried out by special enzymes that couple the release of energy from ATP to cellular activities that require energy.

Detailed explanation-3: -The ATP is used for various cellular functions, including transportation of different molecules across cell membranes. Other functions of ATP include supplying the energy required for the muscle contraction, circulation of blood, locomotion and various body movements.

Detailed explanation-4: -ATP. Specifically, during cellular respiration, the energy stored in glucose is transferred to ATP (Figure below). ATP, or adenosine triphosphate, is chemical energy the cell can use. It is the molecule that provides energy for your cells to perform work, such as moving your muscles as you walk down the street.
