| Description: The relationship between acid–base imbalances and potassium imbalances. Potassium diffuses out of cells in states of respiratory acidosis and metabolic acidosis associated with accumulation of inorganic acids. In metabolic acidosis caused by accumulation of organic acids, both the H+ and the anion from the dissociated acid can diffuse into cells; therefore, K+ exit from the cell is not needed to maintain the electrical charge in the cell. The acidosis figure shows a cell in which hydrogen is entering the cell, bonding with proteins, and pushing out the potassium from the cell. The alkalosis figure shows a cell in which potassium is entering the cell, which has hydrogen bonded to protein in it. This causes the hydrogen and protein to disassociate and the potassium to exit the cell once more.
