• It occurs when a substance can move freely through the lipid bilayer.

• It occurs when a substance cannot move freely through the lipid bilayer.

Why would substance need facilitated diffusion?

• Because the substance is polar or too large

• Because the substance in non polar or too large

• Because the substance is non polar or too small

• Because the substance is polar or too small
