WHY AT THE TIME OF DEPOLARISATION K+ EFFLUX OCCURS. I know that at he time of depolarisation there should be influx of cations so that depolarisation that charge can go from -70mV TO +10mV ,,,, THEN WHY K+ GOES OUT, IF IT REMAINS INSIDE CELL THEN IT WILL BE EASIER TO ATTAIN DEPOLARISATION. EXPLAIN IT PLEASE

Hello,
During depolarization sodium channels open that lead to influx of sodium ions that depolarizes fibre from -70mV to +10mV. However, as the impulse passes pottasium ion move outwards to restore the potential. And then Na+/K+ ATP pumps transfer sodium and pottasium ions to respective sites.
