Many Metabolic Pathways Are Ultimately Concerned with ATP; Either with the Generation

Many metabolic pathways are ultimately concerned with ATP; either with the generation of ATP, or with the requirement of ATP for that pathway to function.Why is ATP so important to metabolism?

A) Hydrolysis of ATP is used to drive exergonic reactions
B) Hydrolysis of the bond between adenine and ribose in ATP is commonly used to release energy that can be used to drive other cellular reactions
C) The phosphate groups of ATP are held together by unstable bonds that can be broken to release energy
D) ATP is a protein that serves as the energy currency of cells ATP does serve as the energy currency of cells, by storing energy in its triphosphate group.By cleaving the unstable bonds holding the phosphates together in the ATP molecule, energy can be released to drive endergonic reactions.ATP can also be used as a building block for RNA molecules.It is not a protein.
