Upon being released from the sarcoplasmic reticulum,Ca²⁺ ions bind to the protein __________. A)troponin B)actin C)myosin D)keratin E)collagen

Question

Quizplus · Accepted Answer

Upon being released from the sarcoplasmic reticulum, Ca2+ ions bind to the protein troponin, which helps to initiate the process of muscle contraction. Actin and myosin are also involved in muscle contraction, but they do not directly bind to Ca2+ ions. Keratin and collagen are structural proteins that are not involved in muscle contraction.
