The concentration of calcium ions Ca inside a cell is typica
The concentration of calcium ions (Ca^++) inside a cell is typically very low, less than 0.001 mM. The Ca++ concentration outside the cell is 2.5 mM. Moving Ca++ out of the cell would require and would be an example of
Solution
The movement of the calcium outside the cell wil occur through Ion pump by the process of active transport. It is a type of transport in which the ions are transported from a region of lower concentration to a region of higher concentration using the energy of the cell. In this case also the calcium are transported against the concentration gradient hence require energy.!! So active transport by ion pump
