Question

Quizplus · Accepted Answer

The thick filament is primarily composed of myosin molecules, which are responsible for generating the force required for muscle contraction. Actin, troponin, and tropomyosin are components of the thin filaments, which interact with the thick filaments during muscle contraction. Thrombin is not a component of muscle anatomy, but rather a blood clotting enzyme.
