Which of the following statements is True?
A) A basolateral GLUT5 transporter moves glucose out of the intestinal epithelial cell.
B) Fructose moves across the apical membrane by active transport.
C) Glucose and galactose use different transporters in absorption.
D) Glucose and galactose absorption uses an apical Na⁺-glucose SGLT symporter.
E) None of the statements are True.

Question

Quizplus · Accepted Answer

Glucose and galactose are absorbed in the small intestine using an apical Na⁺-glucose SGLT symporter. This symporter requires the active transport of sodium ions and allows glucose and galactose to be co-absorbed with sodium ions. Fructose, on the other hand, is absorbed via a different transporter called GLUT5, which is located on the apical membrane of the intestinal epithelial cells. Therefore, statement A is false and statement B is incorrect. Statement C is also false as glucose and galactose are absorbed using the same transporter. Thus, the correct option is D.
