The high-energy compound that interacts most directly with the contractile proteins of muscle is

Question

Quizplus · Accepted Answer

ATP (adenosine triphosphate) is the primary energy currency of the cell, and provides the energy for muscle contraction through the hydrolysis of its terminal phosphate group, releasing energy that can be used by the contractile proteins (actin and myosin) to generate movement. The other compounds listed may also contribute to energy metabolism in some tissues or situations, but they do not have the same direct role in muscle contraction as ATP.
