Question

What type of diffusion is aided with a transport protein?

a. Osmosis
b. Permeated diffusion
c. Facilitated diffusion
d. Osmotic diffusion

Answer 1

Facilitated diffusion is the diffusion of solutes through transport proteins in the plasma membrane. Facilitated diffusion is a type of passive transport. Even though facilitated diffusion involves transport proteins, it is still passive transport because the solute is moving down the concentration gradient.
