Answer to Question 1

ANS: A
Anatomically, contraction occurs when the sarcomere shortens, so adjacent Z lines move closer together. Such a contraction does not occur in relationship to a decrease in A band or Z line length or a decrease in H zone distance.

Answer to Question 2

ANS: C
Troponin T aids in the binding of the troponin complex to actin and tropomyosin. Troponin C contains binding sites for the calcium ions involved in contraction. Troponin I inhibits the ATPase of actomyosin. Troponin M is not a substance.
