Regardless of the location, the sodium-potassium pump is an example of active transport due to its use of the ATP molecule as an energy source.

There has to be a reason for the cell to expend energy in a transport such as the sodium-potassium pump. The reason is simple: the ions are moving against their concentrations, that is, the sodium and potassium ions both move from an area of low concentration to an area of high concentration, against their natural tendencies.
