The action potential
RMP
- =70mV
- resting membrane potential
- ICF = relative negative
- ECF = relative positive
1. Depolarization
- Influx of Na+
- (a)Na+ channels open & increase diffusion rate of Na+ (x800)
- (b)raises positive charges in (-) ICF so much that it becomes positive
- (c)Na+ diffusion rate returns to normal & K+ diffusion rate increases
- Influx of Na+
2. Repolarisation
- (a)rapid efflux of K+
- (b)outside of cell (ECF) becomes more positive
3. Hyperpolarisation
- Efflux of K+ goes too far
