ATP can be used as the cell’s energy exchange mechanism because
- A. endergonic reactions can be fueled by coupling them with the formation of ATP from ADP
- B. ATP is the most energy-rich small molecule in the cell.
- C. ATP is disposable form of chemical energy, used once and then discarded by the cell
- D. endergonic reactions can be fueled by coupling them with the hydrolysis of high-energy phosphate bonds in ATP.
When a cell needs energy, it breaks down ATP to form adenosine diphosphate (ADP), a free phosphate molecule, and releases 12kcal of energy for exercise. However, the amount of ATP stored in the muscle is not much, so to have a healthy long-term muscle, it is necessary to restore and maintain adequate ATP. The energy used to recover ATP is broken down from starch, protein, and fat components.
Here is my explanation about ATP:
