Which of the following characterizes the sodium-potassium pump?

ASodium ions are pumped out of a cell against their gradient.
BPotassium ions are pumped into a cell against their gradient.
CThe pump protein undergoes a conformational change.
DOnly A and B are correct.
EA, B, and C are all correct.

Verified Answer :

E
Sodium ions are pumped out against the concentration gradient while potassium ions are pumped in against the concentration gradient and the proteins may go conformational change during this, making all three options correct.
