Quizplus · Accepted Answer

The separation of actin molecules from myosin molecules requires energy in the form of ATP hydrolysis. This allows the myosin head to detach from actin and return to its original conformation, ready for another cycle of contraction. Calcium, sodium, and acetylcholine are involved in the process of muscle contraction, but they do not directly cause the separation of actin and myosin.
