<prompt> All of the following are true about excitation-contraction coupling in skeletal muscle except thatAcetylcholine is released at the nerve terminalCa2 is released from sarcoplasmic reticulum during contractionCa2 is pumped back into sarcoplasmic reticulum during relaxationCa2 binds to tropomyosin to initiate muscle contraction  <response>: Ca2 binds to troponin C not Tropomyosin to initiate muscle contraction.
