A) +70 millivolt
B) +30 millivolt
C) -30 millivolt
D) -70 millivolt
Correct Answer: D
Solution :
The resting potential of a nerve is -70 millivolt from inside to outside. This potential te generated mainly due to \[N{{a}^{+}}-{{K}^{+}}\] pump and the relative impermeability of a resting nerve to Na4 ions. Hence, more positive charge is accumulated outside the nerve than inside and results in the generation of the above mentioned potential.
