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 ); … WebThis series of reactions is the basis of the ATP-PC system. In summary, ATP synthesises to ADP and resynthesises to ATP with the help of PC molecules and Creatine Kinase. These reaction take place very quickly inside the muscles, and because PC is stored in the muscles it is the first energy system used during high intensity physical activity.

Phosphocreatine, also known as creatine phosphate (CP) or PCr (Pcr), is a phosphorylated form of creatine that serves as a rapidly mobilizable reserve of high-energy phosphates in skeletal muscle, myocardium and the brain to recycle adenosine triphosphate, the energy currency of the cell. See more In the kidneys, the enzyme AGAT catalyzes the conversion of two amino acids — arginine and glycine — into guanidinoacetate (also called glycocyamine or GAA), which is then transported in the blood to the liver. A methyl group is … See more Phosphocreatine can anaerobically donate a phosphate group to ADP to form ATP during the first five to eight seconds of a maximal muscular effort. Conversely, excess ATP can be used during a period of low effort to convert creatine back to phosphocreatine. See more The discovery of phosphocreatine was reported by Grace and Philip Eggleton of the University of Cambridge and separately by Cyrus Fiske and Yellapragada Subbarow of the See more • Human Metabolome Database at the University of Alberta See more WebEnergy is released from ATP when the end phosphate is removed.
