The sodium-potassium pump makes the cell interior more _________ by pumping _______ sodium ions out of the cell for every ___________ potassium ions pumped in.
A)negative, 3, 2
B)negative, 2, 3
C)positive, 3, 2
D)positive, 2, 3
E)negative, 4, 3

Question

Quizplus · Accepted Answer

The sodium-potassium pump contributes to the cell's negative interior by actively transporting 3 sodium ions out of the cell and 2 potassium ions into the cell, using ATP for energy. This results in a higher concentration of positive ions outside the cell compared to inside, thus maintaining the negative charge of the cell interior.

The Sodium-Potassium Pump Makes the Cell Interior More _________ by Pumping
