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.
Best Answer: ATP provides energy when it reacts, so it is used as an energy source for all the processes which require energy from cellular respiration to muscle contraction. In glycolysis, 2 ATP molecules are used to phosphorylate and activate compounds that will eventually become converted to pyruvate.
