How does facilitated diffusion occur through a protein channel?
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.
Does facilitated diffusion require a carrier or channel protein for the movement of molecules across the cell membrane?
Yes, facilitated diffusion requires a carrier or channel protein for the movement of molecules across the cell membrane.
What is the definition of protein gate?
A protein gate is a pathway through a protein molecule on the plasma membrane in which ions and small molecules can diffuse in or out of a cell.
How do water-soluble molecules diffuse through the cell membrane?
Water-soluble molecules diffuse through the cell membrane by passing through protein channels or transporters that are embedded in the membrane. These channels and transporters allow the molecules to move across the membrane, from an area of high concentration to an area of low concentration, without requiring energy.
Why can oxygen diffuse across a cell membrane but a protein?
Its too large
Transport protein that provides a tubelike opening in the plasma membrane through which particles can diffuse?
Channel Protein.

Why do you have diffusion?
so molecules can use protein channel to cross a cell membrane-cleo
What protein recognizes certain molecules bringing them across a membrane?
channel or transport or receptor
What types of molecules diffuse through the cell membranes by facilitated diffusion?
Molecules that are charged or polar, such as ions, glucose, and amino acids, diffuse through cell membranes by facilitated diffusion. This process relies on carrier proteins or channel proteins to help facilitate the movement of these molecules across the membrane.
Why can oxygen diffuse across a cell membrane but a protein?
Its too large
The proccess by which a protein channel allows molecules to cross the cell membrane is called?
Facilitated diffusion
What is this statement most likely referring to Small nonpolar molecules may pass through this structure but others require a protein channel?
Small non-polar molecules may pass through a a semipermeable membrane but others require a protein channel.
What is the fuction of protein channel in the cell membrane?
to either absorb/excrete whole protein molecules that are produced in other/same cell(s).
