Chapter 4.1, Problem 2CYU

Summary Introduction

To draw:

A graph depicting the changes in potential during depolarization, repolarization, and hyperpolarization as compared to resting membrane potential.

Introduction:

All body cells have a membrane potential, which divides the positive and negative charges throughout the membrane. This potential is associated with uneven distribution of sodium (Na⁺), potassium (K⁺) and large intracellular protein anions, between the ICF (intracellular fluid) and the ECF (extracellular fluid) as well as to the plasma membrane's differential permeability. When the cell is electrically resting and does not produce electrical signal, the constant membrane potential is called resting membrane potential.
