Chapter 12, Problem 12.31EP

(a)

Interpretation Introduction

Interpretation: To indicate whether the B vitamin portion of FAD molecule is the “active” subunit of the molecule in redox reactions or not.

Concept introduction: B vitamin is a group of vitamins which are water-soluble in nature and for enzyme cofactors it acts as precursors.

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. Nicotinamide adenine dinucleotide and flavin adenine dinucleotide are examples of coenzyme which are utilized in various metabolic pathways.
