The action potential of a nerve cells is

Options

A. 45 mV
B. 55 mV
C. 80 mV
D. 75 mV

Answer

A

Explanation

Action potential is a membrane potential in which nerve impulse is generated in response of specific stimulus regulated by `Na^(+)//K^(+)` pump in which `3Na^(+)` move in and `2K^(+)` move out thus maintain inside the plasma membrane more position than outside and maintain membrane potential is 45 mV.
