- Action potential
- At resting potential. Na+ channel closed. K+ channel open (some)
- Energy causes Na+ channel to open, and Na+ diffuse in by electrochemical gradient
- Potential difference reverse, influx more Na+
- AP reaches +40mV, Na+ channels close, some K+ channels open
- More K+ channels open, K+ diffuse out of axon, causing repolarisation
- Outward diffusion causes hyperpolarisation
- K+ channels closed, Na-K pumps Na+ out, K+ in.
- Resting potential (-65mV) repolarised
- K+ channels closed, Na-K pumps Na+ out, K+ in.
- Outward diffusion causes hyperpolarisation
- More K+ channels open, K+ diffuse out of axon, causing repolarisation
- AP reaches +40mV, Na+ channels close, some K+ channels open
