Select all that applyChoose the properties of voltage-gated channels.Multiple select question.They open and close in response to small voltage changes in the membrane potential.They allow most ions to pass through depending upon their concentration gradient.They open or close when a ligand binds to a receptor that is part of the ion channel.They are specific for the type of ion that passes through them.
