The rate of diffusion of glucose through artificial phospholipid bilayers is exceptionally low.By contrast,the cells lining the small intestine rapidly transport large quantities of glucose from glucose-rich food into their glucose-poor cytoplasm.Based on this information,which transport mechanism is most likely responsible for glucose transport in the intestinal cells?

Question

Quizplus · Accepted Answer

Facilitated diffusion is responsible for the rapid transport of glucose in intestinal cells, as it involves carrier proteins or channels that increase the rate of glucose movement across the cell membrane, bypassing the slow diffusion through the phospholipid bilayer.
