What is the role of Ca ++ in muscle contraction? A. Ca causes an action potential to travel along the sarcolemma B. Ca binds to troponin changing its shape. C. Ca attaches to the binding site of myosin, energising it. D. Ca engages with the binding site of actin causing the power stroke
OptionB. Calcium binds to troponin changing its shape. Calcium triggers contraction with the aid of using response with regulatory proteins that withinside the absence of calcium save you interaction of actin and myosin. Two distinctive regulatory structures are located in specific muscles.
