Answer:

The speed of the myosin ATPase.

Explanation:

Myosin ATPase is actually considered as molecular motor of muscle cells because it converts chemical energy into directional movement.

ATP comes and bind with the myosin. Now, it is in high-energy state. ATPase hydrolyzed the ATP into ADP by releasing of inorganic phosphate (Pi).

When myosin binds with the actin, then ATPase convert ATP into ADP and this chemical energy converts into directional movement (contraction) of muscle cells.

Myosin ATPase speed depends on the shortening of respective muscle. ATPase activity are higher when intrinsic speed increases.
