Question

the electric potential difference across the cell membrane is known as
the membrane potential.
the plasmalemma potential.
the membrane difference.
the cellular difference.
the cellular potential.

Explanation:

The electric potential difference across the cell membrane is defined as the membrane potential. The other options like plasmalemma potential (plasmalemma is another term for cell membrane but the standard term is membrane potential), membrane difference, cellular difference, and cellular potential are not the correct terminologies for this concept.

Answer:

A. the membrane potential.
