What are the similarities between channel and carrier proteins?
Posted January 9, 2023
There are various similarities between channel and carrier proteins. One similarity is that both channel and carrier proteins are often selective for one or more molecules. They both will change in response to the binding of their target molecule; the shape change moves the molecule to the opposite side of the cell membrane. Another similarity is that both types of proteins form continuous protein pathways across the lipid bilayer. Additionally, both proteins span widely across the cell membrane. Both types of proteins are also very specific for the molecules they transfer. Lastly, as ion concentration increases, the rate of reaction also increases until it reaches saturation.
