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.

Diffusion and facilitated diffusion?
Diffusion:Diffusion describes the spread of particles through random motion from regions of higher concentration to regions of lower concentration. The time dependence of the statistical distribution in space is given by the diffusion equation. The concept of diffusion is tied to that of mass transfer driven by a concentration gradient, but diffusion can still occur when there is no concentration gradient (but there will be no net flux). diffusion is invoked in the social sciences to describe the spread of ideas.Facilitated diffusion:Facilitated diffusion (also known as facilitated transport or passive-mediated transport) is a process of passive transport, facilitated by integral proteins. Facilitated diffusion is the spontaneous passage of molecules or ions across a biological membrane passing through specific transmembrane integral proteins. The facilitated diffusion may occur either across biological membranes or through aqueous compartments of an organism
Why isnt cellular energy required for the passenger molecule to be carried across the cell membrane by the carrier molecule?
Because of facilitated diffusion(, which nutralizes it from a higher to a lower concentration.)
How do particles move from an area of high to an area of low concentration?
In cells, diffusion moves by facilitated diffusion, active transport, ABC transporters, group translocation or osmosis. Some of these move molecules from a low concentration to a higher and against the gradient.Simple diffusion moves molecules from a high concentration to a lower concentration.
Which of the following required the most ATP to move the molecule across a plasma membrane?
Ion moving against a concentration gradient
What is a protein moves molecules across a membrane?
Facilitated diffusion moves molecules through cell membranes passively.
Is facilitated diffusion active?
No. Facilitated diffusion is a type of passive transport.
Facilitated diffusion required what?
Facilitated diffusion requires membrane proteins
Does facilitated diffusion require the use of energy?
Facilitated diffusion does not require the use of energy.
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.
What are the 3 types of diffusion?
simple diffusion, osmosis and facilitated diffusion.
How much ATP does the Facilitated diffusion cost the cell?
Facilitated diffusion is an inactive mode.So no ATP cost.
Does glucose enters a cell most rapidly by facilitated diffusion?
No, glucose enters a cell most rapidly through facilitated diffusion with the help of glucose transporters, such as GLUT proteins. Facilitated diffusion allows glucose to move down its concentration gradient into the cell without requiring energy.
What is the use of carrier proteins for diffusion?
facilitated diffusion.
Diffusion requires what?
Facilitated diffusion requires membrane proteins
Is this true that Facilitated diffusion would be used on large molecules?
its false, facilitated diffusion would be used on small molecules
Diffusion with a channel protein?
Channel proteins facilitate the passive movement of molecules down their concentration gradient. They form channels across the cell membrane, allowing specific molecules to move in and out of the cell without requiring energy input. This process is known as facilitated diffusion.
