Which of the following is NOT true of carbohydrate absorption? 1. End products of carbohydrate digestion are transported through the portal vein to the liver. 2. Disaccharides are digested to monosaccharides by enzymes attached to intestinal cells. 3. Monosaccharides can enter the villi. 4. Lactose is absorbed intact and transported through the portal vein to the liver.

Option D

Explanation:

The goal of the carbohydrate absorption is to breakdown all the disaccharides and other complex carbohydrates of the body into monosaccharides.

Most of the digestion and absorption of the carbohydrate takes place in the stomach and small intestine but some part of it starts from the mouth.

The lactose is also a disaccharide and is not transported with being broken down into glucose and galactose by the action of the enzyme lactase.
