Which is NOT true about the latent period concerning skeletal muscle physiology? ADP bound to myosin heads is replaced by ATP. Myosin heads spontaneously bind to expose active sites forming "cross-bridges." The latent period lasts several milliseconds between action potential initiation at the neuromuscular junction and the beginning of the contraction at the sarcomere. Calcium is released from the sarcoplasmic reticulum and diffuses through the sarcoplasm. The action potential is transmitted along the T-tubules.

Muscle contraction process. which statement is true? neurotransmitter binds to thin filament? t tubules help transmit the action potential deep into the muscles of the cell stimulating the release of calcium? muscle cells can contract without the presence of calcium?

Which statement about skeletal muscle contraction is not true? a. A single action potential at the neuromuscular junction is sufficient to cause a muscle to twitch. b. Once maximum muscle tension is achieved, no ATP is required to maintain that level of tension. c. An action potential in the muscle cell activates contraction by releasing $\mathrm{Ca}^{2+}$ into the sarcoplasm. d. Summation of twitches leads to a graded increase in the tension that can be generated by a single muscle fiber. e. The tension generated by a muscle can be varied by controlling how many of its motor units are active.
