All of the following are true about excitation-contraction coupling in skeletal muscle except that
Ca2+ binds to troponin C (not Tropomyosin) to initiate muscle contraction. Ref: Ganong&;s Review of Medical Physiology 26th edition Pgno: 105
Acetylcholine is released at the nerve terminal
Ca2+ is released from sarcoplasmic reticulum during contraction
Ca2+ is pumped back into sarcoplasmic reticulum during relaxation
Ca2+ binds to tropomyosin to initiate muscle contraction
