Catalysis of the energy-independent passage of cations across a lipid bilayer down a concentration gradient. Catalysis of the transfer of inorganic cations from one side of a membrane to the other. Inorganic cations are atoms or small molecules with a positive charge that do not contain carbon in covalent linkage. Catalysis of the transfer of metal ions from one side of a membrane to the other. Catalysis of facilitated diffusion of ammonium (by an energy-independent process) involving passage through a transmembrane aqueous pore or channel without evidence for a carrier-mediated mechanism. Catalysis of the transfer of ammonium from one side of a membrane to the other. Ammonium is the cation NH4+ which is formed from N2 by root-nodule bacteria in leguminous plants and is an excretory product in ammonotelic animals. Catalysis of the transfer of organic cations from one side of a membrane to the other. Organic cations are atoms or small molecules with a positive charge that contain carbon in covalent linkage. Catalysis of facilitated diffusion of an ion (by an energy-independent process) by passage through a transmembrane aqueous pore or channel without evidence for a carrier-mediated mechanism.
