Answer:
C. It is in the covalent bounds between the phosphate groups
Explanation:
Energy is stored in the covalent bonds between phosphates group's, with the greatest amount of energy (approximately 7 kcal/mole) in the bond between the second and third phosphate groups. This covalent bond is known as a pyrophosphate bond. An analogy between ATP and rechargeable batteries is appropriate.
