Facilitated diffusion is a passive process whereby a molecule is "carried" across a semi-permeable membrane by a channel or protein carrier. Like diffusion, this process requires no energy, however, since passive diffusion can drive movement against a concentration gradient it is not really diffusion.
molecules move from higher concentration to lower concentration.....the answer is concentration
Diffusion is caused by a difference in pressure. A higher pressured element will be driven to diffuse over a permeable membrane to a lower pressure area.

Facilitated diffusion moves molecules through cell membranes passively.

There are three forms of passive transport, or the movement of biochemical and other atomic or molecular substances across the cell membranes. They are: osmosis, simple diffusion or facilitated diffusion, and filtration.
Facilitated diffusion (or facilitated transport) is a process of diffusion, a form of passive transport facilitated by transport proteins. Facilitated diffusion is the spontaneous passage of molecules or ions across a biological membrane passing through specific transmembrane transport proteins. The facilitated diffusion may occur either across biological membranes or through aqueous compartments of an organism.
They are the channels by which molecules enter in facilitated diffusion.
Facilitated diffusion moves molecules through cell membranes passively.
facilitated diffusion
Facilitated diffusion uses integrated proteins that act as channels for ions or molecules to pass through.
No. Facilitated diffusion is a type of passive transport.
it enters most rapidly by facilitated diffusion!!

No. Facilitated diffusion is an example of passive transport because it does not require the cell to expend energy.
Facilitated diffusion requires membrane proteins
The difference between diffusion and facilitated diffusion is that facilitated diffusion is that the molecules pass through special protein channels.
