Aerobic respiration uses an external electron acceptor rather than an internal electron acceptor, as is used in anaerobic fermentation. Explain what this means. Why does using an external electron acceptor provide so much more energy to the cell?

Expert Solution

Summary Introduction

To explain: The meaning of “Aerobic respiration uses an external electron acceptor rather than an internal electron acceptor, as is used in anaerobic fermentation”.

Introduction: Cell is the basic “fundamental unit” of life. Cell performs various metabolic activities that help in its survival. One such important metabolic activity is respiration. It is the flow of electrons to obtain energy by the oxidation of nutrients. Respiration is of two types: aerobic (oxygen dependent) and anaerobic (oxygen independent).

Explanation of Solution

Aerobic respiration is a type of respiration that occurs in the presence of oxygen. It uses an external electron acceptor. However, anaerobic fermentation is a type of fermentation that occurs in the absence of oxygen. The use of external electron acceptor helps in the complete oxidation of pyruvate to CO₂. This type of electron acceptor provides the conditions for the aerobic respiration to generate a set of 38 ATPs with least loss of energy molecules. It provides a more energy supply to the cell than by anaerobic fermentation.

This type of electron acceptor provides the conditions for the aerobic respiration to generate a set of 38 ATPs with least loss of energy molecules. It provides a more energy supply to the cell. This terminal electron acceptor leads to continues redox reaction of NADH. This NADH is electron acceptors and they convert these electrons into higher energy molecules.
