Transport of Monosaccharides into the Enterocyte

Glucose and galactose compete for a common transport system. This system is an active transport system i.e., the monosaccharides are absorbed against a concentration gradient, it is saturable and obeys Michaelis-Menten 

The intracellular glucose is transferred to the portal capillary blood by passive diffusion and by a carrier-mediated system. Intracellular glucose can be converted to lactate 

Fructose transport is distinct from glucose-galactose transport and requires a specific saturable membrane carrier (facilitated diffusion).
