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 (adenosine triphosphate) is required in all living cells as a continual supply of energy, to be used in processes, which keep the organism alive such as muscle contraction. ATP is made up of three main components, the base (adenine), a phosphate chain (made of three phosphate groups) and a ribose sugar backbone.
