When the nervous system tells themusclecell to contract, calcium is released. The calcium activates the troponin complex, which movestropomyosin, and themusclecell can contract. Troponin is attached to theproteintropomyosin and lies within the groove between actin filaments in muscle tissue. In a relaxed muscle, tropomyosin blocks the attachment site for the myosin crossbridge, thus preventing contraction. |
