Identify the incorrect statements pertaining to the coupling process of muscle contractions. Identify all that apply. a. The action potential travels into the transverse tubules of the sarcolemma b. The receptor on the sarcoplasmic reticulum detects the acetylcholine Calcium diffuses with its concentration gradient from the sarcoplasmic reticulum into the sarcoplasm d. Calcium binds to troponin, causing troponin to dissociate from myosin. e Tropomyosin shifts and myosin binding sites on actin are exposed. 25. Identify the correct statements pertaining to ATP use during muscle excitation coupling contraction relaxation. Identify all that apply a. The Na-K* pumps at the sarcolemma use 1 ATP to pump out 3 Na’ions and pump in 2K b. The Cat pumps in the sarcolemma use ATP to pump Ca?out of the muscle fiber after it dissociates from troponin c. Before tropomyosin shifts to expose actin, 1 ATP must bind to tropomyosin’s head d. Before myosin can reorient toward actin, ATP must bind to the myosin head e. ATP is used to pump Captions back into the sarcoplasmic reticulum during relaxation
