When a nerve cell (neuron) or muscle cell react, they do so by a process called depolarization. Before depolarization, the inside of the cell is slightly negative and the outside is slightly positive. During depolarization, sodium ions rush into the cell while potassium channels leak out. This reverses the original polarization and now the cell is said to be depolarized. The sodium/potassium pump helps reverse this back to its original polarized state so the cell can react again.
ATP provides the energy for the sodium potassium pump.
The sodium/potassium pump, the sodium leak channel and the potassium leak channel.
Sodium potassium pump prevents accumulation of K out side of cell and Na inside of cell.
Sodium-Potassium pump uses ATP (energy) to pump sodium out of cells and potassium back in.

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.

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.
