D)are actively transported across cell membranes.

Question

Quizplus · Accepted Answer

Small, nonpolar, hydrophobic molecules such as fatty acids easily pass through a membrane's lipid bilayer because they are soluble in the lipid fatty acid tails of the membrane and can move across the membrane by simple diffusion. They do not require transport proteins or active transport to cross the membrane.
