As is shown … WebK + ion channels are composed of a diverse family of membrane-spanning proteins that selectively conduct K + ions across cell membranes. K + ion channels have a pore that permits K + ions to cross the cell membrane and a selectivity filter that specifies K + ion as the ion species to move through the channel (see margin note). There are several ...
