This powerpoint is a stepbystep, annotated accounting of the working of the sodium potassium pump. Na,katpase is an essential gene maintaining electrochemical gradients across the plasma membrane. These ions travel against the concentration gradient, so this process requires atp. It works constantly in the background to maintain the intracellular and extracellular sodium and potassium ion concentrations and is therefore essential for electrical activity in nerve cells see ch. A large percentage of a cells atp is spent powering this pump, because cellular processes bring a great deal of sodium into the cell and potassium out of the cell. In biology, an ion transporter or ion pump is a transmembrane protein that moves ions across a biological membrane against their concentration gradient through active transport.
