Question

Diffusion that occurs through carrier proteins is

• A. Simple diffusion
• B. Passive diffusion
• C. Facilitated diffusion
• D. Active diffusion

Answer 1

The correct option is C

Facilitated diffusion

The diffusion that is facilitated by the carrier proteins is called facilitated diffusion. This type of diffusion occurs in case of molecules which cannot cross the membrane because of the presence of its hydrophilic moiety.
