The breakdown of creatine phosphate is regulated by
A) the amount of lactate dehydrogenase in the muscle.
B) the amount of NAD in the sarcoplasm of the muscle.
C) ADP concentration in the cytoplasm.
D) the pH of the interstitial fluid.

Question

Quizplus · Accepted Answer

The breakdown of creatine phosphate is regulated by the concentration of ADP in the cytoplasm. When ATP is rapidly being used during muscle activity, ADP builds up and triggers the breakdown of creatine phosphate to provide additional energy to form ATP. This process helps to maintain the energy needed for muscle contractions.
