WebWhat is the role of calcium in muscle contraction? a. Its binding to a regulatory protein causes the protein to move, exposing actin binding sites to the myosin heads. b. It provides energy for contraction. c. It blocks contraction when the muscle relaxes. d. It forms the heads of the myosin molecules in the thick filaments inside a muscle fiber. WebThe movement of myosin heads occurs in two phases: The power stroke occurs when the myosin heads bend and ratchet the actin molecules past the myosin. The recovery stroke involves the myosin heads detaching from actin and being cocked back into the high energy position to prepare for the next power stroke. Skeletal Muscle Contraction.
