Which organelle stores calcium in skeletal muscle fibers for contraction?

Which organelle stores calcium in skeletal muscle fibers for contraction? sarcoplasmic reticulum, intracellular system of closed saclike membranes involved in the storage of intracellular calcium in striated (skeletal) muscle cells.

Where does calcium come from in skeletal muscle contraction? Calcium is released from the sarcoplasmic reticulum through calcium ion channels when the membrane of the T-tubular system is excited. It binds to Troponin C causing it to conform, hence permitting the myosin head to latch onto the actin filament, onsetting muscle contraction.
