(a)

Interpretation Introduction

Interpretation: To identify the structural subunits ${\text{NAD}}^{+}$ and $\text{NADH}$ molecules have in common.

a.

b. ${\text{NAD}}^{+}$ and ${\text{FADH}}_2$

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.

${\text{NAD}}^{+}$ and $\text{NADH}$ are the examples of coenzymes which are employed in various metabolic pathways.
