The molecule that provides the energy for the sliding filament mechanism is:

Question

Quizplus · Accepted Answer

ATP (Adenosine triphosphate) provides the energy needed for the sliding filament mechanism. During muscle contraction, ATP hydrolysis releases energy that powers the movement of the myosin head along the actin filament, leading to shortening of the sarcomere and muscle contraction. Therefore, option A is the correct answer. Options B, C, and D are all incorrect as they are not involved in muscle contraction.
