Enables transport of a solute across a membrane. This kind of transporter interacts much more weakly with the solute than the carrier does. It is an aqueous pore that extends across the membrane. It may change from closed to open and back. It transports faster than a carrier. It is always passive. Catalysis of the transfer of a solute from one side of the membrane to the other, down the solute's concentration gradient. Catalysis of energy-independent facilitated diffusion, mediated by passage of a solute through a transmembrane aqueous pore or channel. Stereospecificity is not exhibited but this transport may be specific for a particular molecular species or class of molecules.
