Physiology All of the following is true about excitation contraction coupling in skeletal muscle, except: A Acetylcholine is released at nerve terminals B Ca++ is pumped backed into SERCA during relaxation C Ca++ is binds to tropomyosin to initiate contraction D Unlike cardiac muscle that has electrochemical coupling, skeletal muscle shows electromechanical coupling 💡 Explanation All of the following is true about excitation contraction coupling in skeletal muscle, except: ✓ Correct Answer: C. Ca++ is binds to tropomyosin to initiate contraction
