WebATP (adenosine triphosphate) is the energy-carrying molecule used in cells because it can release energy very quickly. Energy is released from ATP when the end phosphate is … WebPhosphocreatine (PC) is then broken down by the enzyme creatine kinase into Creatine and Pi 3. The energy released in the breakdown of PC allows ADP and Pi to rejoin forming more ATP. This newly formed ATP can now be broken down to release energy to fuel activity. ATPase in this case assists the synthesis of new ATP rather than the breakdown.
