Creatine phosphate shuttle

The creatine phosphate shuttle is an intracellular energy shuttle which facilitates transport of high energy phosphate from muscle cell mitochondria to myofibrils. This is part of the phosphocreatine metabolism. In mitochondria, ATP levels are very high as a result of glycolysis, TCA cycle, oxidative phosphorylation processes, whereas creatine phosphate levels are low.This makes conversion of creatine to phosphocreatine a highly favored reaction.Phosphocreatine, is a very-high-energy compound.Phosphocreatine, then diffuses from mitochondria to myofibrils.
