How do transporters and channels select which solutes they help move across the membrane?
Both channels and transporters discriminate between solutes mainly on the basis of size and electric charge.
Channels allow the passage of solutes that are electrically charged; transporters facilitate the passage of molecules that are uncharged.
Channels discriminate between solutes mainly on the basis of size and electric charge; transporters bind their solutes with great specificity in the same way an enzyme binds its substrate.
Channels will allow the passage of any solute as long as it has an electric charge; transporters bind their solutes with great specificity in the same way an enzyme binds its substrate.
