Why does the sodium-potassium pump require energy?
Understand the Problem
The question is asking about the sodium-potassium pump, specifically why it requires energy to function. This involves understanding the mechanism of active transport and the specific roles of sodium and potassium ions in cellular processes.
Answer
To move ions against their gradients
The sodium-potassium pump requires energy to move ions against their gradients.
Answer for screen readers
The sodium-potassium pump requires energy to move ions against their gradients.
More Information
The sodium-potassium pump moves sodium and potassium ions against their concentration gradients by using energy from ATP.
Tips
A common mistake is to think that the pump moves ions along their gradients. Remember, it moves them against the gradient, which is why energy is required.
