Which of the following statements best describes the sliding filament mechanism of muscle contraction? a. Actin and myosin filaments do not shorten, but rather, slide past each other. b. Actin and myosin filaments shorten and slide past each other. c. As they slide past each other, actin filaments shorten, but myosin filaments do not shorten. d. As they slide past each other, myosin filaments shorten, but actin filaments do not shorten.

What do skeletal muscle contractions share in common with smooth muscle contractions?a. Both types of contractions do not require calcium ions for a contraction to occur.b. Both types of contractions generate little force or a weak force.c. Both types of contractions consume very little ATP.d. Both types of contractions result from thick and thin filaments sliding past one another.

The functions of tropomyosin in skeletal muscle include A. releasing calcium ions after initiation of contraction. B. generating ATP which it passes to the contractile mechanism. C. binding to myosin during contraction. D. acting as a relaxing protein at rest by covering up the sites where myosin binds to actin. E. sliding on actin to produce shortening.
