In a muscle fibre ca++ is stored in
WebAs long as Ca ++ ions remain in the sarcoplasm to bind to troponin, and as long as ATP is available, the muscle fiber will continue to shorten. Relaxation of a Muscle Fiber: Ca ++ ions are pumped back into the SR, which causes the tropomyosin to reshield the binding sites on the actin strands. WebA muscle fiber is composed of many fibrils, packaged into orderly units. The striated appearance of skeletal muscle tissue is a result of repeating bands of the proteins actin and myosin that are present along the length of myofibrils.
