Maintenance of normal intracellular fluid volume depends largely on the intracellular concentration of ions. a. sulfide and bromide b. hydride and iodide c. oxide and nitride d. potassium and phosphate

The answer is D. Extracellular, the main ions involve in osmoregulation in a cell are sodium and chloride. Intra-and extracellular distribution of K+ is influenced, for example, by Na+/K+-ATPase function, pH, Cellular catabolism and anabolism, Insulin and glucose. Parathormone and calcitriol are important in the homeostatic regulation of phosphates.
