WebCreatine phosphate is the main high-energy, phosphate-storage molecule of muscle. In rested muscle, creatine phosphate is the predominant form (Demant and Rhodes, 1999 ); … 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. high school scheduling ideas
