The main storage site for calcium is the endoplasmic reticulum in muscle cells, specifically known as the sarcoplasmic reticulum. b. Describe the events that must occur in the muscle cell before calcium is released from this organelle.
These discrete regions within the muscle cell store calcium (increasing the capacity of the sarcoplasmic reticulum to release calcium) and release it when an action potential courses down the transverse tubules, eliciting muscle contraction.hese discrete regions within the muscle cell store calcium (increasing the capacity of the sarcoplasmic reticulum to release calcium) and release it when an action potential courses down the transverse tubules, eliciting muscle contraction.
