Answer by Nicole Cooper. Confidence votes 32. The role ATP plays in muscle contraction is that ATP binds to sites on myosin heads, inducing a conformational change in the actin binding site and reducing the affinity for the actin substrate. Hydrolysis of ATP then cocks the myosin head and moves it closer to the z disk.
ATP, also known as adenosine triphosphate, is the primary source of energy for many body functions, muscle contraction included, notes Wikipedia. According to Muscle Physiology, muscle contraction and relaxation are achieved through the Lymn-Taylor actomyosin ATPase hydrolysis mechanism.
