All of the following are true about excitation contraction coupling except:
Ans. d. Calcium binds to tropomyosin to initiate muscle contraction Calcium binds to Troponin C, not to the tropomyosin, to initiate muscle contraction. `The calcium released into the cytosol binds to Troponin C by the actin filaments, to allow cross-bridge cycling, producing force and, in some situations, motion.'
