Question

What is the reaction that converts Phosphocreatine to Creatine and P?

1) Phosphocreatine + P → Creatine
2) Phosphocreatine + P → Creatine + P
3) Phosphocreatine → Creatine
4) Phosphocreatine → Creatine + P

Answer 1

The reaction that converts Phosphocreatine to Creatine and P is 4) Phosphocreatine → Creatine + P. When the muscle needs energy, creatine phosphate transfers its phosphate back to ADP to form ATP and creatine. This reaction is catalyzed by the enzyme creatine kinase.

Step-by-step explanation:

The reaction that converts Phosphocreatine to Creatine and P is 4) Phosphocreatine → Creatine + P.

Phosphocreatine is a molecule that stores energy in its phosphate bonds. When the muscle starts to contract and needs energy, creatine phosphate transfers its phosphate back to ADP to form ATP and creatine. This reaction is catalyzed by the enzyme creatine kinase.
