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 ); … WebWhat is PCr energy system? An anaerobic energy system in which the generation of ATP is coupled with the exergonic (energy-releasing) breakdown of phosphocreatine stored in muscle cells. The breakdown frees inorganic phosphate, which then combines with ADP to form ATP. The ATP-PCr system is the quickest source of ATP for muscle actions. WebPhosphocreatine is known as its quickest form of regeneration, by means of the enzyme creatine kinase. Thus, the primary function of this system is to act as a temporal energy buffer.
