BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Monosaccharide sugars such as galactose, glucose, and fructose are absorbed by active transport across the microvillus membrane of the small intestine into the portal blood system for transport to the liver.

Detailed explanation-2: -Active transport of glucose mediated by SGLT1 in the apical membrane of enterocytes appears as the main molecular mechanism of glucose absorption in the small intestine.

Detailed explanation-3: -Fructose is absorbed by facilitated diffusion.

Detailed explanation-4: -Glucose, galactose, and fructose are the three monosaccharides that are commonly consumed and are readily absorbed.

Detailed explanation-5: -Absorption of Carbohydrates Glucose, fructose, and galactose are absorbed across the membrane of the small intestine and transported to the liver where they are either used by the liver, or further distributed to the rest of the body (3, 4).
