Absorption of Glucose from the Gut Lumen Depends on All

Question

Absorption of glucose from the gut lumen depends on all of the following except
A) the sodium-potassium pump in the basolateral membrane of the epithelial cell.
B) cotransporter proteins in the apical membrane of the epithelial cell.
C) higher sodium ion concentration in the lumen than in the epithelial cell.
D) sodium-linked cotransport.
E) emulsification forming small micelles.

Accepted Answer

Emulsification forming small micelles primarily affects the absorption of lipids and fatty acids, not glucose. The absorption of glucose from the gut lumen is primarily dependent on sodium-linked cotransporters in the apical membrane of the epithelial cell, the higher sodium ion concentration in the lumen than in the epithelial cell, and the sodium-potassium pump in the basolateral membrane of the epithelial cell.
