D)actin

Question

Quizplus · Accepted Answer

Myosin is responsible for ATP hydrolysis, as it contains ATPase activity in order to break down ATP and release energy necessary for muscle contraction. Tropomyosin and troponin C are regulatory proteins that are involved in controlling muscle contraction, while actin is the protein that interacts with myosin to generate muscle force.
