Question

Which membrane valves that open and close for potassium efflux and sodium influx

Answer 1

Hey there!

☞As the stimulus is given to a neuron.. Then when the membrane potential once reaches to -55 mv... Then voltage gated Na channels open and there is a rapid influx of sodium Ions..

☞ At +30mv (repolarisation) ,voltage gated Na channels close and voltage gated K channels open.. And then there is a rapid eflux of K+ions ...
