simple diffusion
Diffusion - Biology: AQA A Level
The difference between simple and facilitated diffusion is that facilitated diffusion: A Requires a protein transporter B Moves molecules
One way facilitated diffusion functions is to move molecules across the cell membrane by using channel proteins These proteins are embedded in the plasma We use simple diffusion to allow carbon dioxide and oxygen go in and out of our cells without the use of energy Active transport is the movement of molecules
