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.
Examples are the splitting of ATP in muscle contraction and the transport of ions across cell membranes. adenosine triphosphate (ATP) a nucleotide, adenosine 5â²-triphosphate, occurring in all cells, where it stores energy in the form of high-energy phosphate bonds.
