The plasma membrane na +/k +-atpase pump
WebbThis balance is regulated by modifying the presence and activity of potassium ion transporters in the plasma membrane of cells, particularly the Na + –K + pumps. Several factors have been shown to impact the internal distribution of potassium, including insulin, catecholamines, acid–base balance and serum osmolality. WebbThis is accomplished by an ATP-dependent Ca 2+ pump in the plasma membrane. Thus, as in other cells, maintaining cell volume in the face of impermeant intracellular colloids …
