Question

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

Answer 1

Answer:

Option B, storing energy that will transferred to ADP to resynthesize ATP

Explanation:

Creatine phosphate is a phosphorylated creatine molecule. It is present in muscle cells for storing energy. Creatine is an amono acid which is produced by the liver, kideny and pancreas.

Energy is stored in creatine phosphate for rapid release. Normal metabolism does not release energy as soon as released by creatine phosphate.

So, lots of creatine phosphate is present in energy rich muscle whereas very few present in fatigued muscle.

Creatine phosphate transfers its phosphate group to ADP quickly to regenerate ATP.

So, among the given option, option B is correct.
