After presenting general … WebThis review discusses selective and fast transport of ionic species (ions and their associates) through systems as diverse as ion-conducting transmembrane proteins and ion exchange membranes (IEMs) in aqueous environments, with special emphasis on the role of electrostatics, specific chemical interactions, and morphology (steric effects). Contrary to … Web11 apr. 2024 · Active and passive transport can take place, but the latter can also be performed by carrier proteins. Because valinomycin is highly selective and only transports potassium ions, it is used instead of a channel. Carriers can bind to a wide range of target substances, including sodium-potassium pumps, but their binding sites are highly specific. firstrand compo etn on berkshire hathaway inc
