Creatine phosphate, also known as phosphocreatine, is a high-energy compound stored in muscle cells that serves as a rapid source of energy during short bursts of intense exercise. It plays a crucial role in muscle metabolism by donating a phosphate group to adenosine diphosphate (ADP) to regenerate adenosine triphosphate (ATP), the primary energy currency of the cell. This process allows for quick energy replenishment, helping muscles to perform optimally during activities like sprinting or heavy lifting.
