Facilitated diffusion (or facilitated transport) is a process of diffusion, a form of passive transport facilitated by transport proteins.
Facilitated diffusion (facilitated transport) is a process of passive transport (diffusion) via which molecules diffuse across membranes, with the help of transport proteins (mediated transport).
Facilitated Diffusion of Glucose
Assume:
a concentration of glucose inside the cell of 0.5 millimolar (mM) and a
concentration of glucose outside the cell of 5 millimolar (mM) ...
facilitated diffusion
The spontaneous passage of molecules and ions, bound to specific carrier proteins, across a biological membrane down their concentration gradients.
facultative anaerobe ...
Facilitated diffusion Transport of an ion or a molecule down a concentration gradient, where .G for the transported species is negative. Also called passive transport.
facilitated diffusion Mediated transport in which a permease makes possible diffusion of a molecule across a cell membrane in the direction of a concentration gradient; contrast with active transport.
Facilitated diffusion involves the use of a protein to facilitate the movement of molecules across the membrane. In some cases, molecules pass through channels within the protein.
See: facilitated diffusion, symport, antiport.

Some of these proteins can move materials across the membrane only when assisted by the concentration gradient, a type of carrier-assisted transport known as facilitated diffusion.
It is a process called facilitated diffusion. It could be as simple as bringing in a glucose molecule. Since the cell membrane will not allow glucose to cross by diffusion, helpers are needed.
