Sodium-potassium pumps indirectly provide the energy source for SGLT carriers in intestinal cells.

Question

Quizplus · Accepted Answer

The sodium-potassium pump works to maintain the concentration gradients of sodium and potassium ions across the cell membrane, which indirectly provides the energy needed for glucose transport by SGLT carriers in intestinal cells. This is because the movement of glucose into the cell is coupled with the movement of sodium ions down their concentration gradient, which is maintained by the sodium-potassium pump. Therefore, the activity of the sodium-potassium pump is essential for the functioning of SGLT carriers.
