Diffusion, Facilitated Diffusion & Active Transport

Simple passive diffusion occurs when small molecules pass through the lipid bilayer of a cell membrane Facilitated diffusion depends on carrier proteins

Simple Diffusion: Phospholipid Bilayer Non-polar molecules can simply diffuse across a membrane Non-polar molecules can simply pass through the
