During the resting membrane potential, the inside of the neuron is while the outside is
a. positive, negative
b. negative, positive
c. negative, negative
d. positive, positive

The correct answer is option b.

Explanation:

Resting membrane potential is the membrane potential of a cell at rest or quiescent stage. Usually, a cell maintains a resting membrane potential as negative, that is, -70mV

It is because a cell has more sodium ions outside the cells as compared to the potassium ions present inside the cell.

A sodium-potassium pump helps in achieving this potential. It moves 2 potassium inside the cell in comparison to the movement of 3 sodium outside the cell at the cost of 1 ATP.

At the time of stimulus, sodium channels get opened due to which sodium ions rush into the cell and leads to depolarization. At the the time of depolarized state, the inside of the cell is positive and outside of the cell is negative.
