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. Using this information, which transport mechanism is most probably functioning in the intestinal cells?A. Simple diffusion
B. Phagocytosis
C. Active transport pumps
D. Exocytosis
E. Facilitated diffusion
