(a)
Interpretation: To identify the subunit that involves a B vitamin in the six-subunit block diagram for CoA.
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. CoA is also an example of the coenzyme.
