A given set of 100% muscle cells responding repeatedly without relaxing Score: 38. 1/1 Shifting of the troponin-tropomyosin complex. As a direct result of Ca+2 binding to troponin: Student Response Value A. Calcium ions 0% enter the axon B. Calcium ions are pumped back into the sarcoplasmic reticulum. 0% C. Acetylcholine is 0% released into the synaptic cleft by exocytosis. D. Acetylcholine binds to postsynaptic receptors on the sarcolemma. 0% E. Na+ moves 0% across the sarcolemma into the muscle cell.
