Chapter 27, Problem 27.23P

Interpretation Introduction

Interpretation:

The only ${\text{C}}_{\text{5}}$ compound in the citric acid cycle is to be predicted.

Concept introduction:

Anabolism and catabolism are the two pathways of metabolism. In anabolic pathway, large molecules are formed by the combination of small molecules. Anabolism is totally opposite to that of catabolism process. On the other hand, the catabolic pathway involves the breakdown of larger molecules into smaller molecules.

In the Krebs cycle, acetyl-CoA helps to convert larger molecule of proteins, lipids and carbohydrates into smaller molecules. In each step of this cycle, a specific enzyme is involved.
