Chapter 11, Problem 25RQ

Summary Introduction

To review:

The mechanism of movement of potassium across the plasma membrane of a nerve cell during repolarization and depolarization.

Introduction:

The mechanism by which the nerve cells function is the formation of action potentials. These potentials are generated through differential ion concentrations within andoutside the cells. Membrane depolarization and repolarization shift these concentrations around in order for the cell to perform its intended function.
