Chapter 23, Problem 23.24E

Interpretation Introduction

Interpretation:

The primary function of the citric acid cycle in $\text{ATP}$ production is to be described and the other vital role served by the citric acid cycle is to be explained.

Concept introduction:

The oxidation of fuel molecules begins when the two carbon acetyl units enter the citric acid cycle. This process is called citric acid cycle because one of the key intermediate is citric acid. The citric acid cycle is the principal process for regenerating the reduced coenzymes $\text{NADH}$ and ${\text{FADH}}_{\text{2}}$, which are necessary for the reduction of oxygen and $\text{ATP}$ synthesis in electron transport chain.
