<prompt> All of the following are true about potassium, exceptMostly concentrated inside the cellsLeaves the cell in the presence of insulinIngestion of acetazolamide results in potassium lossPlasma concentration increases at time of metabolic acidosis  <response>: Insulin increases permeability of the cell to potassium, magnesium,phosphate ions.the effect of potassium is clinically impoant, insulin activates sodium potassium pump causing influx of potassium Ref:Guyton and Hall textbook of medical physiology 12th edition,page number: 610,611,612
