The sodium ( Na ) potassium ( K) pump is an active transport system which requires energy in the form of ATP breakdown.

An unequal distribution of $"Na"^(+)$ and $"K"^(+)$ ions occurs on the two sides of the nerve cell membrane.

This difference in charge generates electrical impulses which lead to nerve impulses.

The Na - K pump illustrates active transport since it moves $"Na"^(+)$ and $"K"^(+)$ ions against their concentration gradient.

The energy required is supplied by the breakdown of ATP (adenosine triphosphate) to ADP (adenosine diphosphate).

In nerve cells the pump is used to generate gradients of both sodium and potassium ions.

The sodium and potassium ions are pumped in opposite directions across the membrane.
This pump build a chemical and electrical gradient.
These gradients can be used to drive other transport processes.
In nerve cells the pump is used to generate gradients of both sodium and potassium ions.
