Which of the following helps to transport long-chain fatty acids from the interior of the small intestinal lumen to the absorptive cells?
A) chylomicrons
B) micelles
C) villi
D) bile salts
E) symporters

Question

Quizplus · Accepted Answer

Micelles are formed by bile salts in the lumen of the small intestine and help to transport long-chain fatty acids and other lipids to the absorptive cells in the intestinal lining. Chylomicrons are larger lipoprotein particles that are formed within the absorptive cells and transport lipids away from the intestine, while villi are finger-like projections in the intestinal lining that increase surface area for absorption. Symporters are transport proteins that help to move molecules across membranes by using the electrochemical gradient. Bile salts are necessary for micelle formation and the transport of lipids.
