WebThe answer is "The inactivation gate of the voltage-gated sodium channel is open." During the rapid depolarization phase of an action potential, the voltage-gated sodium channels are activated, causing an influx of sodium ions into the cell. At the same time, the voltage-gated potassium channels are closed, preventing the efflux of potassium ions. WebA set of voltage-gated potassium channels open, allowing potassium to rush out of the cell down its electrochemical gradient. These events rapidly decrease the membrane potential, bringing it back towards its normal …

WebJan 17, 2024 · The prototypic ligand-gated ion channel is the nicotinic acetylcholine receptor. It consists of a pentamer of protein subunits with two binding sites for acetylcholine which, when bound, alter the receptor’s configuration and cause an internal pore to open. This pore allows Na + ions to flow down their electrochemical gradient into the cell.
