Question

Quizplus · Accepted Answer

Binding of ATP to myosin is necessary for the detachment of the myosin head from actin, which is a crucial step in the muscle contraction cycle. This allows the cycle of cross-bridge formation and breakdown to continue, enabling muscle contraction and relaxation.
