The sodium-potassium pump functions as an antiporter.What does this pump use to drive ion movement?
A) Formation of an ion concentration gradient
B) Phosphorylation of ADP
C) Transport of glucose
D) Conformational change of a protein
E) Facilitated diffusion of water

Question

Quizplus · Accepted Answer

The sodium-potassium pump uses ATP to induce a conformational change in the protein, allowing it to transport sodium and potassium ions across the cell membrane against their concentration gradients.
