Ion ChannelsWhat is the difference
between Chemical gated ion
channelsAnd voltage-gated ion
channels?
Chemical gated ion channels:
Open when the appropriate neurotransmitter binds to the receptor
Open and close in response to changes in membrane voltage
Voltage-gated ion channels
Which picture is represented by each?
Chemical gated ion channels:
Voltage-gated ion channels
