Why is ATP such a good energy currency of the cell?

Answer 1

ATP is a good energy currency because it is a high energy compound. The hydrolysis of ATP to ADP and Pi yields 7.3 kcal/mole.

Answer 2

1. ATP can be recycled over and over again ... broken, rebuilt, broken, rebuilt, broken, rebuilt ...
2. ATP only releases a tiny amount of energy at a time, so it's easy to control the amount of energy given to a reaction

Answer 3

Formation of Adenine-P-P-P is high in energy in that each of the P (phosphate) attach is conserved in a high energy bond which when hydrolyzed and coupled to metabolic processes drives a forward reaction.
