Question
Chapter 42.2, Problem 3LO
Summary Introduction
To determine: The mechanisms for the generation of action potential by voltage-gated channels
Introduction: The neural membrane contains several passages called the ion channels. These ion channels are the pores formed by the protein found in the membrane of the neuron. The passages help in the conduction of nerve impulses.
