Question

Why is active transport necessary for the sodium-potassium pump to work?

A. The sodium would never leave a cell while potassium can move against the gradient
B. All channel movement requires active transport to equalize the cell
C. It allows sodium and potassium to move against their concentration gradient
D. The potassium would never leave a cell while sodium can move against the gradient

Answer 1

Active transport is necessary for the sodium-potassium pump to work because it allows sodium and potassium to move against their concentration gradients.
