Question

Which of the following statements regarding glucose absorption is true?

chose the correct answer :

A)Glucose is absorbed mostly through the lining of the small intestine.
B)Glucose is absorbed mostly in the stomach.
C)Glucose is digested in the small intestine.
D)Glucose is absorbed solely through the lining of the mouth: the oral mucosa.

Answer 1

Glucose is absorbed through the lining of the small intestine using active transport and facilitated diffusion, with the help of absorptive cells lined with microvilli that increase surface area.

Step-by-step explanation:

The correct answer to which statement regarding glucose absorption is true is: A) Glucose is absorbed mostly through the lining of the small intestine. Carbohydrates, including glucose, are absorbed as monosaccharides in the small intestine. This process involves active transport and facilitated diffusion. Absorptive cells in the small intestine have microvilli that increase surface area, enhancing the absorption of nutrients. Once absorbed, glucose is transported into the epithelial cells via protein carriers and then enters the capillaries, ultimately to be distributed throughout the body.
