Ions enter cells via cell membrane ion channels that are either gated or nongated.
Voltage-gated and ligand-gated ion channels react to voltage differences and ligand binding, respectively. Voltage-gated ion channels are ion-selective, while ligand-gated ion channels are not.
Voltage-gated ion channels open in reaction to a voltage differential, while ligand-gated channels open in response to ligand binding.
Voltage-gated ion channels enable just one kind of ion to pass through the channel pore, while ligand-gated channels are less selective and allow two or more types of ions to pass through the channel pore.
