During action potential, positively charged ________ ions move inside the cell.
Tems11 [23]

During action potential, positively charged  sodium ions move inside the cell.

So option D is correct one.

The sodium ion moves inside the cell during a action potential. The stage of action potential is called depolarization . This open voltage gated sodium channel.

Action potentials ( those electrical impulse that send signals around body )  is nothing but more than temporary shift ( from negative to positive ) in the neuron's membrane potential caused by ions suddenly flowing in and out of the neuron.

It consists of phases:

  • Depolarization
  • overshoot
  • repolarization

An active potential propagates along the cell membrane of an axon until  it reaches the terminal button.
