Answer #1

Phosphocreatine is the energy source for muscle contractions and is also known as creatine phosphate. It provides energy in the form of ATP.

The phosphocreatine system provides enery anaerobically that is why it is also called as the anaerobic alatic system, which is in function during the initial 10 seconds of sustained muscle contractions. Muscles need ATP (energy) to function but the supply is very limited and is used up quickly. This ATP supply is hence facilitated by phosphocreatine. In this process, a high energy phosphate of creatine phosphate is transferred to ADP. As a result, ATP and creatine are formed. ATP is used by muscles and creatine is removed from the body through kidneys and the urinary system as it is a waste material.

A: Phosphocreatine is used by your muscle cells to store energy. The dephosphorylation of phosphocreatine, like that of ATPATP, is a highly exergonic reaction with ΔG∘′=−10.3kcal/molΔG∘′=−10.3kcal/mol: Phosphocreatine+H2O⇌creatine+PiPhosphocreatine+H2O⇌creatine+Pi ATP+H2O→ADP+PiATP+H2O→ADP+Pi Choose a reaction for the transfer of phosphate from phosphocreatine to ADPADP to generate creatine and ATPATP.
