Which of the following are involved in the regulation of cross bridge attachment activity?

Question

Quizplus · Accepted Answer

Calcium ions, troponin, and tropomyosin are all involved in the regulation of cross bridge attachment activity in muscle contraction. Calcium ions bind to the troponin, causing a conformational change that moves tropomyosin away from the cross bridge binding site on actin, allowing for cross bridge attachment and muscle contraction. Therefore, all of the above options are involved in the regulation.
