10.3 Muscle Fiber Contraction and Relaxation – Anatomy and Physiology
This multipart figure shows the mechanism of skeletal muscle contraction. In the top panel, the ADP and inorganic phosphate molecules are bound to the myosin motor head. In the middle panel, the ADP and phosphate come off the myosin motor and the direction of the power stroke is shown. In the bottom panel, a molecule of ATP is shown to bind the myosin motor head and the motor is reset.
