The Rate of Diffusion of Glucose Through Artificial Phospholipid Bilayers

question 86

Multiple Choice

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?

• A)simple diffusion
• B)phagocytosis
• C)active transport pumps
• D)facilitated diffusion
