The sodium-potassium pump uses ENERGY to move ions, it is a form of active transport. It moves sodium ions, generall highly concentrated outside the cell, to the outside, and potassium ions highly concentrated within the cell, within. Thus, it moves ions from areas of low concentration to high concentration, a process unlike diffusion and osmosis.....it requires ATP or the energy currency of a cell.
A sodium-potassium pump transports sodium and potassium ions across cell membranes, generally to create an electrical gradient (such as in heart muscle cells or neurons).
No, it uses [highly specific as opposed to bulk] Active Transport Systems times two: one each for each of the 'pumps' - transmembrane Gated Channels are used.

the sodium-potassium pump is one of the most important carrier proteins in the animal cell.
Repolarization The questioner was looking for the mechanism not the process. The answer is the sodium potassium pump.
potassium ions into the cell
The sodium-potassium pump (PDB entries 2zxe and 3b8e ) is found in our cellular membranes, where it is in charge of generating a gradient of ions. It continually pumps sodium ions out of the cell and potassium ions into the cell, powered by ATP.
Na+ out of the cell and K+ into the cell
Sodium-Potassium pump uses ATP (energy) to pump sodium out of cells and potassium back in.
Sodium Potassium pump
Thesodium-potassium pump uses active transport to move 3 sodium ions to the outside of the cell for each 2 potassium ions that it moves in.
ATP provides the energy for the sodium potassium pump.

sodium-potassium pump
The sodium-potassium pump is a transmembrane protein in a cell membrane. It keeps large concentrations of sodium ions outside the cell, and potassium ions inside the cell. It does this by pumping the sodium ions out, and the potassium ions in.
The sodium/potassium pump, the sodium leak channel and the potassium leak channel.
3 sodium ions for 2 potassium ions.
In a sodium-potassium pump a carrier protein uses ATP in Active transport. The sodium ions are transported out of the cells and the potassium ions are transported into the cell.
The sodium potassium pump requires ATP - i.e. it is involved in active transport, not facilitated transport.
