Define about skeletal muscle?

A. The binding of calcium ion to a binding site on the troponin molecule leads to a movement of the tropomyosin molecule that, in turn, exposes a binding site on the actin molecule for ATP.

B. The head of a myosin molecule is activated (energized) during the hydrolysis of ATP (which is bound to the myosin head) to cAMP and Pi.

C. Consider the situation in which a myosin head is attached to its receptor site on the actin molecule. For this situation, the binding of ATP to a binding site on the myosin head causes detachment of the myosin head from the actin molecule.
