[Answer] Where is calcium stored?

Answer: Smooth ER
Where is calcium stored?

Calcium ions (Ca ) contribute to the physiology and biochemistry of organisms cell. They play an important role in signal transduction pathways where they act as a second messenger in neurotransmitter release from neurons in contraction of all muscle cell types and in fertilization. Many enzymes require calcium ions as a cofactor including several of the coagulation factors. Extracellular calcium is also important for maintaining the potential difference across excitable cell membranes as well as proper bone formation.

Calcium is a very ductile silvery metal (sometimes described as pale yellow) whose properties are very similar to the heavier elements in its group strontium barium and radium. A calcium atom has twenty electrons arranged in the electron configuration [Ar]4s . Like the other elements placed in group 2 of the periodic table calcium has two valence electrons in the outermost s-orbital which are very easily lost in chemical reactions to form a dipositive ion with the stable electron configuration of a noble gas in this c…

Calcium is stored in geologic reservoirs most commonly in the form of calcium carbonate or as calcium silicate. Calcium-containing rocks include calcite dolomite phosphate and gypsum. Rocks slowly dissolve by physical and chemical processes carrying calcium ions into rivers and oceans.
