How a sodium potassium pump can maintain a voltage gradient across a cell or neuron's membrane. The sodium-potassium pump goes through cycles of shape changes to help maintain a negative membrane potential. In each cycle, three sodium ions exit the cell, while two potassium ions enter the cell. These ions travel against the concentration gradient, so this process requires ATP.

sodium-potassium pump, in cellular physiology, a protein that has been identified in many cells that maintains the internal concentration of potassium ions [K +] higher than that in the surrounding medium (blood, body fluid, water) and maintains the internal concentration of sodium ions [Na +] lower than that of the surrounding medium.

The sodium-potassium (Na +-K+) pump is an example of P-type ATPase pump that moves three Na+ions out and two K+ions into the cell for each ATP hydrolyzed.

The sodium and potassium gradients across the plasma membrane are used by animal cells for numerous processes, and the range of demands requires that the responsible ion pump, the Na,K-ATPase, can be fine-tuned to the different cellular needs. Therefore, several isoforms are expressed of each of the three subunits that make a Na,K-ATPase, the alpha, beta and FXYD subunits.
