The generation of excitation-contraction coupling involves all the following events except

  • generation of end-plate potential

  • release of calcium from troponin

  • formation of cross-linkages between actin and myosin

  • hydrolysis of ATP to ADP

Solution

B.

release of calcium from troponin

When the depolarization spreads along the sarcolemma and down the T tubules, creating an action potential. The action potential triggers the sarcoplasmic reticulum to release of Ca2+, which activate troponin and stimulate muscle contraction.
