WebJun 22, 2024 · Adenosine triphosphate (ATP) is the primary source of chemical energy that body muscles use to perform contractions. During such contraction processes, ATP molecules are depleted as they undergo hydrolysis reactions and become adenosine diphosphate (ADP). WebIn the space below, diagram how phosphocreatine may be utilized to rephosphorylate ATP (be sure to include enzymes). The fastest way to reform ATP is through the ATP-PC system. PC, phosphocreatine, has a phosphate bond which is high in energy. This phosphate bond cleaves from the creatine molecule and attaches to ADP, adenosine di phosphate.
