Question

what are simple and facilitated diffusion?

Answer 1

Simple diffusion is when a small,
non-polar molecule passes through a lipid bilayer.
It is classified as a means of passive transport.In simple diffusion, a hydrophobic molecule
can move into the hydrophobic region of
the membrane without getting rejected. Simple diffusion does not involve a protein.
Ex...osmosis
*********************************************************************************************************
Facilitated diffusion is a type of passive transport that is dependent on single transport protein carriers.
These protein carriers operate on a bind, flip, release mechanism.
Facilitated diffusion is non-diffusional because the molecule moves along with the carrier.
