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. 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 the use of specific transport proteins to move glucose across the cell membrane without the expenditure of energy, allowing for efficient uptake from the intestine.
