Muscle Question!!! HELP!?!?!? Give some background by explaining the events that occur in contracting muscle cells. What molecule blocks the myofilaments, actin and myosin, from interacting? How is it moved when you want to contract a muscle? What role does calcium play in this, and where is it stored in the muscle cell?

Answer 1

calcium is stored in the lumen of the ER and released when a second messenger (IP3) binds to the IP3-gated calcium channel on the membrane of the ER. the release of calcium activates various proteins and the muscle contracts
