(0.25 pts each; 1.5 pt total) Hydrolysis of ATP provides energy for the power stroke of the cross-bridge cycle in both skeletal and cardiac muscle. Type lb skeletal muscle fibers are glycolytic fibers that are found in the smallest motor units. Blood from the right ventricle next passes into the pulmonary trunk/arteries. The fast depolarization phase of cardiac pacemaker cells is due to entry of Na+ into the cell. Both cardiac and skeletal muscle have Ryanodine receptors in their plasma membrane Tetanus results in greater force production by muscle and can be produced in both skeletal and cardiac muscle.Explanation / Answer
