5. Lipoic acid contains as critical group(s)
   1. two thiols                                c. a thioester and a Lys residue
   2. a Lys residue                           d. two thiols and a Lys residue

Answer 1

1 st question options are irrelevant.

Highest energy compound is PEP .

That is phosphoenol pyruvate gives 14.8 kcal.

Atp gives 7.3 kcal.

And glucose 6 phosphate gives approx 4 kcal.

Highest is PEP.

TPP contains essential component vitamin - B1

Thiamine pyrophosphate is thiamine derivate which is B1.

CoA is component of vitamin - panthonenic acid.

Panthonenic acid is metabolically active component of Co A which is essential for the metabolism of carbohydrates, fats, and proteins.

Lipoic acid contains critical groups as 2 sulphur thiol groups and a lysine group to which it is tightly bound.
