Question

During depolarisation of an axonal membrane


1 The K+ channels are open



2 The Na+ voltage gated channnels are open


3
The K+ voltage gated channels are open


4
Both (2) & (3)

which is correct

Answer 1

During depolarization, the membrane potential rapidly shifts from negative to positive. ... As the sodium ions rush back into the cell, they add positive charge to the cell interior, and change the membrane potential from negative to positive.

Answer 2

Answer:

I love You Krish I love you
