Chapter 39, Problem 2ITD

Summary Introduction

To review:

Reviewing the effects of injecting broken down ATP (components of ATP) into the squid axon that is already in cyanide solution.

Introduction:

Action potential generated in the neuron due to the inflow of sodium ions into the axon through sodium ion transporters, and results into excitation of the neuron. These transporters maintain the sodium concentration inside the axon and do not let sodium ions get out of the axon. The sodium transporters get inactivated in the presence of cyanide, and sodium present inside the axon gets out from the neuron.
