# How does the sodium-potassium pump work in nerves cells?

Aug 8, 2016

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

#### Explanation:

An unequal distribution of ${\text{Na}}^{+}$ and ${\text{K}}^{+}$ 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 ${\text{Na}}^{+}$ and ${\text{K}}^{+}$ ions against their concentration gradient.
