Question

Why breakdown of ATP releases energy​

Answer 1

Explanation:

ATP is at a high level of chemical potential but the type of energy released from its hydrolysis depends on the application. The short answer is that the hydrolysis of ATP to ADP always releases heat, and if coupled with a cellular process it additionally produces either chemical potential (in another species) or work.

Answer 2

ATP is a form of energy .So during its breakdown exothermic reaction happens and releases energy.
