WebOct 7, 2024 · dreamrob Answer: In a muscle fiber Ca+ + is stored in Sarcoplasmic reticulum. When muscle cells are stimulated the calcium ions are released inside the sarcoplasmic reticulum. Sarcoplasmic reticulum is a membrane-bound arrangement found in muscle cells. 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. Muscle contraction usually stops when signaling from the motor neuron ends, which repolarizes the sarcolemma and T-tubules, and closes the voltage-gated calcium channels in the SR. dfi gh960
