Opening of sodium gates typically leads to
WebVoltage-gated sodium channels have two gates (gate m and gate h), while the potassium channel only has one (gate n). Gate m (the activation gate) is normally closed, and opens when the cell starts to get more positive. Gate h (the deactivation gate) is normally open, and swings shut when the cells gets too positive. Web3 de jan. de 2024 · The former channels are receptor-ion gates that open when they bind an effector molecule. Mechanically-gated ion channels detect physical pressure or stress …
