WebMay 17, 2024 · 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. Ca ++ ions are then pumped back into the SR, through the process of active transport, which requires ATP. WebWhen 2 calcium ions, along with a molecule of ATP, bind to the cytosolic side of the pump (i.e. the region of the pump outside the SR), the pump opens.
