What does the term "potential" mean as applied to the description of an electrically excitable cell?

A. It is a measure, usually in millivolts, of separation of charge across a membrane.
B. It is a measure, usually in milliamps, of current movement through a membrane.
C. It is a measure, usually in milliohms, of resistance to electrical current movement through a membrane.
D. It is a measure, usually in mmol/L, of ion concentrations in ICF and ECF.



Answer :

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.
