The movement of myosin heads occurs in two phases: 1. The power stroke occurs when the myosin heads bend and ratchet the actin molecules past the myosin. 2. The recovery stroke involves the myosin heads detaching from

Cross bridges are created when myosin heads bind to ________. cross …

WebCross Bridge Formation is the activation of the myosin head when it binds to the actin forming the cross bridge. Inorganic phosphate (P) is released making the bond between actin and the myosin head stronger.
