<P> Calcium storages are intracellular organelles , that constantly accumulate Ca ions and release them during certain cellular events . Intracellular Ca storages include mitochondria and the endoplasmic reticulum . Characteristic concentrations of calcium in model organisms are : in E. coli 3mM ( bound ) , 100nM ( free ) , in budding yeast 2mM ( bound ) , in mammalian cell 10 - 100nM ( free ) and in blood plasma 2mM . </P>
