Question

________ is composed of multiple globular molecules polymerized to form long chains or filaments.
A) Actin
B) Tropomyosin
C) Troponin
D) Myosin
E) Titin

Accepted Answer

Actin is composed of multiple globular molecules polymerized to form long chains or filaments. Tropomyosin and troponin are regulatory proteins associated with actin in muscle contraction. Myosin is a motor protein that interacts with actin to generate force in muscle contraction. Titin is a large protein that functions as a molecular spring in muscle tissue.
