Question

Coenzyme A: Acyl carrier:: Methylcobalamin: _____________

(a) Transketolase reaction

(b) Isomerization

(c) Carboxylation reaction

(d) Carrier of one carbon group

I have been asked this question by my college professor while I was bunking the class.

I would like to ask this question from Enzymes in division Enzymes of Enzyme Technology

Answer 1

The correct choice is (b) Isomerization

To explain I would say: Coenzyme A which is also pantothenic acid vitamin has the function of carrying acyl groups. Methylcobalamin which is a coenzyme performs function of isomerization along with the transfer of methyl groups in a reaction. Transketolase reaction, Carboxylation reaction and Carrier of one carbon group are the functions of thiamine pyrophosphate, biocytin and tetrahydrofolate coenzymes.
