Calcium ion is released from the sarcoplasmic reticulum 4. The correct sequence of these events is A. 9 3 Skeletal Muscle Fibers Contain Calcium Regulated Molecular Motors Human Anatomy And Physiology Anatomy And Physiology Skeletal Muscle Calcium binds to troponin. . Thick filaments are made of the protein. This action requires energy which is provided by ATP. Calcium ion binds to troponin 6. Myosin corss-bridges bind to the actin 2. Active sites on the actin become available for binding after calcium binds to tropomyosin calcium binds to troponin troponin binds to tropomyosin actin binds to troponin myosin binds to troponin 6 After death muscle fibers run out of ATP and calcium begins to leak from the sacroplasmic reticulum into the sacroplasm. Calcium binds to troponin Because after binding of calcium the troponin changes its shape to remove tropomyosin from the actin and exposed the actin for binding of myosin with it.
