Summary Introduction

To explain:

The reason behind the elimination of Pasteur effect in absence of Cytochrome oxidase.

Introduction:

Louis Pasteur observed that when oxygen is added to anaerobic cells consuming high amount of glucose, rate of glucose consumption declines. Along with the decline in consumption of glucose, accumulation of lactate ceases.
