A Cell Which is More Negatively Charged Than at Rest

Question

A cell which is more negatively charged than at rest is ________.
A)Polarized
B)Hyperpolarized
C)Depolarized
D)Refractory

Accepted Answer

Hyperpolarization refers to a situation when the membrane potential of a cell becomes more negative than its resting potential. This happens when there is an increase in the efflux of positively charged ions or an influx of negatively charged ions. As the cell becomes more negative, it becomes less likely to fire an action potential.
