Glucose Is a Six-Carbon Sugar That Diffuses Slowly Through Artificial

Glucose is a six-carbon sugar that 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. Given this information, which transport mechanism is most probably functioning in the intestinal cells?

A) simple diffusion
B) exocytosis
C) active transport
D) facilitated diffusion
E) osmosis
