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.
The alternative view, that the physiologically important calcium store is a specialised organelle, the calciosome, is not supported by these observations. Recent evidence also suggests that ER calcium might be important in ER structure and in the retention of the luminal ER proteins.1)Laboratory of Molecular Biology, Cambridge, UK. Calcium storage is one of the functions commonly attributed to the endoplasmic reticulum (ER) in nonmuscle cells. Several recent studies have added support to this concept.
