WebIn any functional excitable system, at least one of the channel types present must changeits conformation in responseto aphysiological "stimulus" such as anapplied … WebSome ion channels are selective for charge but not necessarily for size, and thus are called a nonspecific channel. These nonspecific channels allow cations—particularly Na +, K +, and Ca 2+ —to cross the membrane, but exclude anions. Ion channels do not always freely allow ions to diffuse across the membrane.
