Creatine phosphate functions in the muscle cell by
A)forming a temporary chemical compound with myosin.
B)forming a chemical compound with actin.
C)inducing a conformational change in the myofilaments.
D)storing energy that will be transferred to ADP to resynthesize ATP as needed.

Question

Quizplus · Accepted Answer

Creatine phosphate acts as a reservoir of high-energy phosphate groups in muscle cells. When ATP levels drop during intense exercise, creatine phosphate transfers its phosphate group to ADP to quickly resynthesize ATP without the need for oxygen or glucose. This process provides a rapid source of energy for muscle contraction.
