How do fatty acids travel through a cell membrane?
A) diffusion
B) active transport
C) carrier proteins
D) endocytosis

Question

Quizplus · Accepted Answer

Fatty acids are small molecules and can passively diffuse through the cell membrane from a region of high concentration to a region of low concentration. No energy or carrier proteins are required for this process. Active transport and endocytosis are not likely mechanisms for the transport of fatty acids through the cell membrane.
