-Contractile protein(s).

Question

Quizplus · Accepted Answer

Actin and myosin are the two main contractile proteins found in skeletal muscle.

Answer: D 
 The troponin-tropomyosin complex is not a contractile protein, but rather a regulatory protein that controls muscle contraction by blocking or allowing access to the actin binding sites on myosin.

Answer: E 
 Actin, troponin, and tropomyosin are all regulatory proteins involved in controlling muscle contraction, but not directly involved in the contractile process itself.

Answer: F 
 This answer includes all four proteins mentioned (actin, myosin, troponin, and tropomyosin), but specifically includes the regulatory proteins as well as the contractile proteins involved in muscle contraction.
