Question
Chapter 3, Problem 15CYU
Summary Introduction
To review:
Whether the inner side of the plasma membrane is negative or positive relative to outer surface of the polarized membrane.
Introduction:
All cells are said to be polarized due to the exhibition of resting membrane potential by their plasma membrane in the resting state. The membrane potential ranges from –50 to –100 mV (millivolts) based on the cell type. The negative value indicates that the interior of the cell is negative compared to the extracellular region.
