Ca2+ binds to this component of the thin filament of skeletal muscle, resulting in the interaction of actin and myosin, and thus, muscle contraction.

Question

Quizplus · Accepted Answer

Ca2+ binds to the troponin complex, which is located on the thin filament of skeletal muscle. This binding causes a conformational change in the troponin complex, resulting in the movement of tropomyosin and the exposure of binding sites on actin for myosin. This interaction between actin and myosin leads to muscle contraction.
