Which statement about muscle contractions is false? O An action potential in the muscle cell activates contraction by releasing Car within the muscle. O A single action potential at the neuromuscular junction is sufficient to cause a muscle to twitch. O Summation of twitches leads to a graded increase in the tension that can be generated by a single muscle fiber. The tension generated by a muscle can be varied by controlling how many of its motor units...
