Glucose is a six-carbon sugar that diffuses slowly through artificial phospholipid bilayers. The cells lining the small intestin
e, however, rapidly move large quantities of glucose from the glucose-rich food into their glucose-poor cytoplasm. Given this information, which transport mechanism is most probably functioning in the intestinal cells
Facilitated diffusion is the process of spontaneous passive transport of molecules or ions through a biological membrane through specific transmembrane integral proteins.
Glucose is a large molecule, so it would be very difficult for it to go through the phospholipid bilayer, as so, facilitated diffusion is the transport mechanism that functions in the absorption of glucose in the intestinal cells.
