Answer:
Energy is released when a phosphate group is cleaved from the ATP molecule
Step-by-step explanation:
Adenosine triphosphate or ATP is known as the energy molecule of the cell or currency of the cell as it provides the energy during metabolic reactions.
The energy is stored in the ATP molecule in the triple bonds formed between two phosphates through phosphoanhydride bond.
The energy is released from the ATP molecule when the ATP molecule is cleaved and the phosphate ions are released releasing a great amount of energy from adenosine diphosphate.
Thus, Option-A is the correct answer.
