Facilitated Diffusion Differs from Simple Passive Permeability in All of the Following

Question

Facilitated diffusion differs from simple passive permeability in all of the following EXCEPT
A) Facilitated diffusion is saturable, passive permeability is not
B) Facilitated diffusion uses metabolic energy, passive permeability does not
C) Facilitated diffusion is specific, passive permeability is not
D) Facilitated diffusion displays competitive inhibition, passive permeability does not
E) Facilitated diffusion uses a carrier, passive permeability does not

Accepted Answer

Facilitated diffusion, like simple passive permeability, does not use metabolic energy. Both processes rely on the concentration gradient, without the need for ATP.
