Question: Place muscle contraction steps in order. A) ACH that is stored in the synaptic vesicle of the synaptic end bulb is released and diffused across the synaptic cleft B) Entry of Na+ ions causes depolarization of sarcolemma. C) Now that the binding sites are free, ATP is hydrolyzed into ADP and a phosphate.
