[A] : Most of the solutes in ECF and cytoplasm are electrolytes, i.e., electrically charged par- ticles or ions. Maintenance of an equilibrium between intracellular fluid and ECF is vitally essential for all cells. [R]: This osmotic equilibrium is maintained by sodium and potassium pump of the cells. It operates with the help of a Na^+, K^+ ATP as enzyme located in the cell membrane.
