Do you ask for 'facilitated diffusion essay'? Here you can find the questions and answers on the subject.
Expedited diffusion is the passive movement of molecules along the concentration gradient. Information technology is a discriminating process, , the membrane allows exclusive selective molecules and ions to passing through it. IT, however, prevents another molecules from casual through the tissue layer. The electric accusation and pH helps in the dissemination across the tissue layer.

How are transmembrane channels used to facilitate diffusion?
Transmembrane channels that allow facilitated diffusion, can be permanently open, or can be closed and opened as in neurones, and as such are known as ‘gated', they open or close in reaction to a ligand, a signalling molecule which can be either extracellular or intracellular.
Which is an example of a facilitated diffusion process?
Facilitated diffusion is the passive movement of molecules along the concentration gradient. It is a selective process, i.e., the membrane allows only selective molecules and ions to pass through it. It, however, prevents other molecules from passing through the membrane.
How does the electric charge help in diffusion?
The electric charge and pH helps in the diffusion across the membrane. In living systems, the lipid based membrane creates compartments which allow the transport of a selective concentration of water-soluble substances. The ions, small molecules, proteins, and other solutes have different concentration across the membranes.
What are the molecules that cannot diffuse across the cell membrane?
The molecules should be small and non-polar to traverse the membrane. For eg., glucose is a large molecule that cannot diffuse across the cell membrane. Ions like sodium, potassium, and calcium are charged and are repelled by the cell membrane.
