During the conduction of nerve impulse, the repolarisation occurs with theA. influx of `K^(+)` ionsB. influx of `Na^(+)` ionsC. efflux of `K^(+)` ionsD. efflux of `Mg^(2+)` ions |

Answer» Correct Answer - C When a stimulus is applied, sodium-potassium pump stops operating. Sodium ions rush inside and potassium ions rush outside. This results in depolarisation (action potential). After a period of action potential, sodium-potassium pump operates (efflux of `Na^(+)` and influxes of `(K^(+)`) and axon will get resting potential by repolarisation. |
