Question

Why is the energy from a molecule of ATP required by the sodium-potassium pump? - It helps the sodium and potassium ions bind to the pump binding sites. - It provides the energy required to move sodium and potassium ions against their concentration gradients. - It provides the energy required to lonize sodium and potassium. - It helps prevent other molecules from being transported by the pump.

Answer 1

It provides the energy required to move sodium and potassium ions against their concentration gradients.

Step-by-step explanation:

Since the sodium potassium pump moves molecules against the concentration gradient, it is a form of active transport. This means is requires energy in the form of ATP.
