The second most powerful energy system is the … WebSome activities use 1, 2 or even all 3 energy systems at different times during the activity, with the emphasis changing according to the intensity relative to fitness levels. Oxygen debt. When anaerobic energy systems are used, an oxygen deficit is produced – muscles need more oxygen than they can get at that time.
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.
