Which Statement Applies to Facilitated Diffusion

Question

Which statement applies to facilitated diffusion?
A) It requires ATP.
B) It can involve either carrier proteins or channel proteins.
C) It is nonspecific with respect to the nature of the molecules being transported.
D) It is not dependent on a concentration gradient.

Accepted Answer

Facilitated diffusion involves the movement of molecules across the cell membrane via specific proteins, either carrier or channel proteins, without the need for energy (ATP). It is specific to the molecules being transported and relies on a concentration gradient.
