Which transport mechanism is most probably functioning in the intestinal cells using this information? Glucose diffuses slowly through artificial phospholipid bilayers. The cells lining the small intestine, however, rapidly move large quantities of glucose from the glucose-rich food into their glucose-poor cytoplasm. A. Simple diffusion B. Phagocytosis C. Active transport pumps D. Exocytosis E. Facilitated diffusion

Answer;

C. Active transport pumps

Explanation; The epithelial cells of the villi transport nutrients from the lumen of the intestine into the capillaries. Digested material may be transported into blood vessels in the wall of the small intestine by the processes of simple/passive diffusion, facilitated diffusion, primary active transport, or secondary active transport. Glucose and galactose are transported by active transport in the epithelial cells of the lumen. Fructose is transported by facilitated diffusion. Transport from epithelial cells into the bloodstream is by facilitated diffusion.
