How does the sodium-potassium pump work in nerves cells?
The sodium ( Na ) potassium ( K) pump is an active transport system which requires energy in the form of ATP breakdown.
An unequal distribution of
This difference in charge generates electrical impulses which lead to nerve impulses.
The Na - K pump illustrates active transport since it moves
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.

The sodium-potassium pump in nerve cells actively transports three sodium ions out of the cell and two potassium ions into the cell against their respective concentration gradients, using energy from ATP hydrolysis. This maintains the resting membrane potential and supports nerve cell functions.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
