Yes, energy is
required to separate the charges. Mostly, the inner of the cell membrane
is negatively charged compared to the outside. When the cell becomes depolarized,
ions, especially, Sodium ions, are pumped
out by active transportation to restore resting potential. Active transport requires energy from ATP powered by food metabolism.
