(D) The correct answer is $(d)$.In living muscle fibres,$ATP$ performs a dual role.Firstly,at rest,when myosin is not acting as an enzyme,$ATP$ binds to the myosin head,which keeps the muscles supple and extensible.Secondly,when the muscle is stimulated,$ATP$ hydrolysis provides the necessary energy for the cross-bridge cycle,which leads to muscle contraction.
