Facilitated diffusion depends on which structure?
A) Vesicles
B) Protein molecule in the cell membrane
C) Cholesterol molecule in the cell membrane
D) Gaps in capillary walls

Question

Quizplus · Accepted Answer

Facilitated diffusion relies on protein molecules embedded in the cell membrane to assist in the movement of certain molecules across the membrane. Vesicles are used in endocytosis and exocytosis, cholesterol molecules do play a role in membrane stability but not in facilitated diffusion, and gaps in capillary walls are more relevant to the movement of molecules in the circulatory system rather than across the cell membrane.
