Ion Channels Which picture is represented by each? What is the difference between Chemical gated ion channels And voltage-gated ion channels? Answer Voltage-gated ion channels Chemical gated ion channels: Chemical gated ion channels: Open when the appropriate neurotransmitter binds to the receptor Click once to show question Click the cloud and the burst to show answer Click the yellow burst a second time to show new question Click answer to show answer Voltage-gated ion channels Open and close in response to changes in membrane voltage
