Question

What does the sodium-potassium pump use?

Answer 1

ATP

Explanation:

The sodium-potassium pump exchanges sodium ions for potassium ions and vice versa. The ions are pumped against the concentration gradient, meaning that it requires energy = active transport.

The molecule adenosine triphosphate (ATP) is the main source of energy for cellular processes. The breakdown of ATP to ADP (adenosine diphosphate) releases energy that is used to fuel the pump.
