MICROANATOMY

Detailed explanation-1: -Which of the following organelles has the function of storing intracellular calcium? Explanation: The endoplasmic reticulum, while crucial to protein synthesis, is also an intracellular calcium storage organelle, and calcium can be released in response to signaling cascades as needed.

Detailed explanation-2: -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.

Detailed explanation-3: -The metazoan endoplasmic reticulum (ER) serves both as a hub for maturation of secreted proteins and as an intracellular calcium storage compartment, facilitating calcium-release-dependent cellular processes.

Detailed explanation-4: -The storage sites include mitochondria and the endoplasmic reticulum. The endoplasmic reticulum (ER) is the largest store of releasable calcium in the cell.
