B)Inside the neuron is more negative than outside the neuron.
C)Both the inside and outside of the neuron are of equal electrical charge.
D)The inside of the neuron is hyperpolarized.

Question

Quizplus · Accepted Answer

During resting potential, the neuron has a negative charge inside compared to the outside, with a potential difference of around -70mV. This negative charge is maintained by the concentration gradient of ions such as sodium and potassium, which are unequally distributed across the membrane. This negative resting potential allows the neuron to fire an action potential when depolarized by incoming signals.
