When a muscle fiber is stimulated with repeated stimuli, the contraction force is summed due to: a) an increasing number of engine units recruit b) the number of actin / myosin bonds decreases c) increased strength of the action potential in the plasma membrane d) The Ca2 + concentration around and in the myofibrils increases
