Final answer:

Membrane potential is the difference in electric potential across a cell, crucial for nerve impulse conduction.


Explanation:

Membrane potential is the difference in electric potential between the interior and exterior of a biological cell, typically ranging from -40mV to -80mV. It arises from the separation of ions across the cell membrane, with positive charges outside and negative charges inside, essential for nerve impulse conduction.
