Facilitated diffusion occurs through a protein channel by allowing specific molecules to pass through the cell membrane with the help of a protein channel. The protein channel acts as a tunnel that facilitates the movement of molecules that are too large or polar to pass through the membrane on their own. The molecules bind to the protein channel, which changes shape to allow them to pass through, ultimately helping them move across the membrane.
Diffusion carried out by protein channel is termed channel mediated diffusionRead more http://www.kgbanswers.com/what-is-channel-mediated-diffusion/4450816#ixzz1EANNtr00
This is correct. Glucose, being a large molecule, requires a protein channel called a glucose transporter to facilitate its passage through the cell membrane. Glucose transporters assist in transporting glucose molecules across the hydrophobic lipid bilayer of the cell membrane.
In the facilitated diffusion the transport protein is needed as well in the active transport.
when a protein channel allows molecules to cross through the cell membrane this is called facilitated diffusion. many might mistake this for diffusion which is the process by which molecules tend to move from an area where they are more concentrated to an area where they are less concentrated.
Diffusion, facilitated diffusion, Osmosis and Active Transport. Diffusion moves non-polar molecules across the cell membrane down a concentration gradient. Osmosis moves water across the cell membrane through a channel formed by aquaporins called a protein channel, down the water potential gradient. Active moves the non-polar molecules against the concentration gradient, in contrast to diffusion. Lastly, facilitated diffusion moves polar molecules across the cell membrane through creating protein channels in the cell membrane from specific proteins. ETC, glucose transporters bind to form a protein channel for glucose to diffuse through, after which the proteins disperse. That should be all, hope it was of help!

Facilitated diffusion moves molecules through cell membranes passively.
The difference between diffusion and facilitated diffusion is that facilitated diffusion is that the molecules pass through special protein channels.

When glucose enters a liver cell through a protein channel, it is called facilitated diffusion. This process involves specific transport proteins, such as GLUT2, that help glucose cross the cell membrane without the use of energy. Facilitated diffusion allows glucose to move down its concentration gradient, enabling efficient uptake by liver cells.

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.Diffusion of molecules assisted by protein channels that pierce a cell membrane
Facilitated diffusion is diffusion that occurs not through the cell membrane directly but through protein channels within the cell membrane. They are often, although not always, substrate specific.
Facilitated diffusion is a process where molecules move across a cell membrane with the help of transport proteins. These proteins create a channel or carrier to allow specific molecules to pass through the membrane. This movement is passive and follows the concentration gradient, meaning that molecules move from an area of high concentration to low concentration.
Glucose molecules are molecules that pass through a protein instead of between the phospholipids. This is because they are to big to diffuse through phospholipids.
