What is the reason for resting membrane potential?

Answer:
The resting membrane potential difference between the inside and the outside of the cell is the result of selective permeability of the cell membrane and the active transport of ions into and out of the cell. Almost all cells have a potential difference, but some cells, neuron and heart muscle, also have voltage and chemically gated channels that allow for transient deviations from the resting potential.
