Describe the resting membrane potential and how it is
generated and maintained.

Expert Solution
Step 1

Introduction:

When there is the placement of two electrodes on the cell's surface and connected via a suitable amplifier to a cathode ray oscilloscope (CRO), the potential difference is not observed. But, when one electrode is inserted into the cell's interior, a constant (steady) potential difference is observed between the external and internal sides of the cell at rest, referred to as resting membrane potential. It is also referred to as steady potential or transmembrane potential and is indicative of a resting state- the state of polarization of the cell membrane.
