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
a concentration of glucose inside the cell of 0.5 millimolar (mM) and a
concentration of glucose outside the cell of 5 millimolar (mM) ...
The spontaneous passage of molecules and ions, bound to specific carrier proteins, across a biological membrane down their concentration gradients.
facultative anaerobe ...
facilitated diffusion Diffusion of molecules across a plasma membrane with the assistance of carrier proteins (the term facilitated diffusion is used in opposition to passive transport).
Allows diffusion of large, membrane insoluble compounds such as sugars and amino acids
Does not require energy (passive)
Substance binds to membrane-spanning transport protein ...
If charged particles or large molecules are to move across the membrane, another process needs to be found, as they are less soluble (or even insoluble) in lipid. They move through protein-lined pores.
Channel proteins ...
facilitated diffusion the movement of molecules across a membrane from a region of high concentration to a region of low concentration that is assisted by proteins.
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.
Facilitated diffusion the diffusion of a substance across a membrane, facilitated (assisted) by a protein carrier molecule
Fatty acid organic compounds that are usually found as constituents of lipids ...

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.
passive transport (facilitated diffusion) - movement of a molecule across a membrane down its concentration gradient
peripheral membrane proteins-proteins that can be released from the membrane ...
It can either be done by simple diffusion or facilitated diffusion. Molecules will go from a region of high concentration to a region of low concentration as they move randomly and eventually become evenly distributed within the system if they are ...
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.
When a molecule moves down its concentration gradient using one of these membrane channels or transporters, the process is called facilitated diffusion. In facilitated diffusion, no input of energy is needed to move the molecules.
Because there's a lot of water on the outside not so much on the inside, that's like facilitated diffusion. Well how would you get that water to move from inside the boat where there's not so much back into the ocean?
Glucose enters cells by facilitated diffusion via glucose carrier proteins
Cells have vesicles with extra carrier molecules present in their cytoplasm
Insulin binds to receptor in plasma membrane ...
Protein-aided transport of an ion or molecule across a cell membrane down its concentration gradient at a rate greater than that obtained by passive diffusion; also called facilitated diffusion.
The passive movement of molecules down their concentration gradient via transport proteins is called facilitated diffusion.
