Question

Referring to the figure shown, the movement of glucose is from the lumen of the duodenum through an interstitial cell, out to the extracellular fluid, and into a capillary.

What would happen if the action of the Na⁺–K⁺ pumps was reduced?

A)The rate of flow of glucose into the interstitial cells would be increased.

B)The direction of flow of glucose would be reversed.

C)The rate of flow of glucose into the interstitial cells would be reduced.

D)Nothing would differ: the movement of glucose would be the same as before the reversal.
