How, specifically, does ATP store energy?
ATP refers to Adenosine triphosphate. It contains ribose sugar, adenine base, and phosphate group, PO4-2 here is a diagram of its molecular structure so basically, the phosphate group on the far left breaks off when an enzyme tell it to do so. This reaction releases energy. Its tat simple After it breaks, adenosine diphosphate (ADP) and orthophosphate (HPO4) as the products. The conversing of ATP to ADP is a cycle, where ADP with energy and that phosphate group can produce ATP.
