Facilitated Diffusion is the movement of molecules across cell membranes through protein channels and carrier proteins.
Facilitated diffusion is a passive transport process, aka no energy required, where substances move down their concentration gradient (high concentration to low concentration) across a protein through a membrane protein because it is unable to diffuse directly through the phospholipid portion of the membrane itself.

∙ 15y agoFacilitated 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.

Is Facilited diffusion is an example of passive transport?
Yes, facilitated diffusion is an example of passive transport. The cell does not expend any energy; integral proteins in the cell's surface membrane act as carriers.
How does facilited diffusion differ from diffusion?
Facilitated diffusion is a process whereby a substance passes through a membrane with a aid of an intermediary or a facilitator. The facilitator is an integral membrane protein that spans the width of the membrane. The force that drives the molecule from one side of the membrane to the other is the force of diffusion. and Diffusion is the process of movement of a substance from the region of higher concentration to the region of lower concentration so as to spread uniformly. Difference : Facilitated diffusion is when polar or charged molecules cross the cell membrane through a trans membrane channel protein. Diffusion is when small, non-polar molecules cross the cell membrane directly through the lipid bilayer. they can do so as they are hydrophobic and hence can pass through the hydrophobic core of the lipid bilayer. crossing the lipid bilayer is difficult for charged/polar particles as they are hydrophilic and large (as they may have hydration shells due to their charged nature), hence they have to cross through transport proteins.
What are the types of cultural diffusion?
contagious diffusion, relocation diffusion, expansion diffusion, stimulus diffusion, hierarchical diffusion.
The spreading out of a substance from an area of high concentration to an area of low concentration is called .?
diffusion
Diffusion of AIDS is an example of which type of diffusion?
Relocation Diffusion
What is the movement of molecules from greater to lower?
Diffusion.
Three types of passive transport?
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.
What are the 3 types of diffusion?
simple diffusion, osmosis and facilitated diffusion.
What is the process of spreading out to fill a sapce uniformly?
Diffusion.
What is the difference between diffusion and facilitate diffusion?
The difference between diffusion and facilitated diffusion is that facilitated diffusion is that the molecules pass through special protein channels.
Molecules tend to move from an area where they are more concentrated to an area where they are less concentrated This process is called?
Diffusion
What is the process of spreading new ideas called?
Diffusion is the process of spreading new ideas from culture to culture. Examples of diffusion include the use of cars and the smelting of iron. There are five main types of diffusion they are: Expansion diffusion, Relocation diffusion, Hierarchal diffusion, Congious diffusion and Stimulus diffusion.
