Expert

Verified

The sodium-potassium pump is the transport protein which maintains the concentration gradient of such ions between the intra and extracellular spaces. Such protein is phosphorylated in each pumping cycle and then it pumps three sodium ions exterior the cell and puts two potassium ions inwards. The phosphorylation is made up by the binding of phosphate donated by one ATP molecule which then is transformed into ADP (that is, adenosine diphosphate).

The job of the sodium-potassium pump, as well termed as sodium-potassium ATPase, is primary to keep the characteristic negative electrical charge in the intra-cellular side of the membrane of the resting cell and to create make conditions of sodium and potassium concentrations outside and inside the cell to maintain the cellular metabolism.
