(a)

Interpretation Introduction

Interpretation:

The state (either oxidized or reduced) of $NA{D}^{+}$ after dehydrogenating a molecule should be given.

Concept Introduction:

$NA{D}^{+}$ Molecule: It is the oxidized form of $\text{Nicotinamide adenine dinucleotide }\left(NADH\right)$ which exists in all cells and needed for activation of enzymes.

(b)

Interpretation Introduction

Interpretation:

The way $NA{D}^{+}$ behaves as oxidizing agent or reducing agent should be given
