P-type ATPases Na+/K+

Insert 2 potassium ions and remove 3 sodium ions Na+ gradient drives transport of nutrients as with glucose. Regulates cytosolic pH More than 30% of an animal cells energy is used to fuel this pump – nerve cells and cells involved in transport this could increase up to 70%. Electrogenic - drives a net electric current across the membrane. As with the calcium pump an aspartate is phosphorylated
