Fat absorption through the plasma membrane of epithelial cells ________.
A) Is accomplished by cotransporters that use the concentration gradient of Na+ outside of the cells
B) requires vesicular, active transport of the relatively large fatty acids and monoglyceride
C) occurs by simple diffusion because lipids are able to penetrate the hydrophobic fatty acid tails within the plasma membrane
D) requires enzymes attached to the brush border to further breakdown the fats

Question

Quizplus · Accepted Answer

Fat absorption through the plasma membrane of epithelial cells occurs by simple diffusion because lipids, being hydrophobic, can easily penetrate the hydrophobic fatty acid tails within the plasma membrane without the need for transport proteins or energy expenditure.
