The sarcoplasmic reticulum releases calcium ions into the cytosol, whereupon it attaches to troponin, causing tropomyosin to expose the myosin-binding sites on actin. After ATP hydrolysis and the formation of crossbridges, the contraction cycle is ready for its next step. During this step which of the following occur to generate the powerful energy needed for action: A. ATP is hydrolyzed into ADP and P B. P is released by the myosin head C. ADP is released from the crossbridge at the myosin head D. ATP binds to the myosin head 13. During rigor mortis following death, muscles are in a state of rigidity, unable to contract or stretch.

ATP binds to the myosin head, the cross-bridge releases, and the process can thereby repeat B. ATP binds to the myosin head, the cross-bridge releases, but there is not enough remaining calcium to continue action potentials C. ATP synthesis ceases soon after breathing (oxygen intake) stops, making it impossible for cross-bridges to release D. Not enough ATPase is present to hydrolyze ATP into ADP and P, so the myosin head cannot orient itself correctly 14.
