The sodium-potassium pump is found in many cell (plasma) membranes. Powered by ATP, the pump moves sodium and potassium ions in opposite directions, each against its concentration gradient. In a single cycle of the pump, three sodium ions are extruded from and two potassium ions are imported into the cell.

Looking at the process starting from the interior of the cell: • The pump has a higher affinity for Na⁺ ions than K⁺ ions, thus after binding ATP, binds 3 intracellular Na⁺ ions. • ATP is hydrolyzed, leading to phosphorylation of the pump at a highly conserved aspartate residue and subsequent release of ADP. This process leads to a conformational change in the pump. http://www.kidneyatlas.org/book5/adk5-02.ccc.QXD.pdf
