Protein channels help move particles across the cell membrane
Facilitated diffusion is the process by which transport proteins help large molecules like glucose cross the cell membrane. These proteins create a channel or carrier mechanism that allows the molecule to move across the membrane along its concentration gradient.
Facilitated diffusion across a biological membrane requires specific carrier proteins or channel proteins to help transport molecules across the membrane. These proteins facilitate the movement of molecules down their concentration gradient, from an area of high concentration to an area of low concentration, without the need for energy input.
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.
Membrane channel proteins facilitate the movement of specific molecules across cell membranes by creating a passageway for them to travel through. They help regulate the flow of ions and other substances in and out of cells, allowing for essential cellular processes to occur.
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!

no one likes you so we didnt find an answer
Carrier proteins help facilitate the movement of certain substances across the cell membrane by binding to specific molecules and carrying them across. These proteins undergo conformational changes to transport the substances across the membrane.

when proteins help molecules move across the membrane, it it called Facilitated Diffusion
Ion channels, such as sodium-potassium pumps, help maintain concentration gradients of ions across a neuronal membrane. These channels actively transport ions across the membrane, moving them against their concentration gradients to establish and regulate the resting membrane potential.

Ions across a cell membrane. It is a form of passive transport. Ions such as sodium(Na+), potassium (K+), calcium (Ca2+), and chloride (Cl-). Each ion channel is usually specific for one type of ion.
Osmosis moves water molecules across the phospholipid bilayer of a cell membrane. Protein channels help facilitate the movement of water and other molecules by providing a pathway through the membrane.
The four main types of proteins found in a cell membrane are integral proteins, peripheral proteins, glycoproteins, and channel proteins. Integral proteins are embedded within the lipid bilayer, while peripheral proteins are attached to the surface of the membrane. Glycoproteins have carbohydrate chains attached to them, and channel proteins help facilitate the movement of specific substances across the membrane.
