Chapter 12, Problem 12.36EP

(a)

Interpretation Introduction

Interpretation: To identify the structural subunits $\text{FAD}$ and ${\text{FADH}}_2$ molecules have in common.

Concept introduction: Coenzymes are non-protein organic compounds that are used along with the enzymes and help to carry forward the reaction. Coenzymes cannot perform on their own alone.

$\text{FAD}$ and ${\text{FADH}}_2$ are the examples of coenzymes which are employed in various metabolic pathways.
