Question

The designation ECa.b.c.d conveys information. Which of the following is not one of it?

(a) One of twelve main classes of biochemical reactions

(b) The group of substrate molecule

(c) The nature of chemical bond that is involved in the reaction

(d) Designation for acceptor molecules (cofactors)

I got this question in an interview for internship.

This interesting question is from Functional Classification of Genes in division Genome Analysis of Bioinformatics

Answer 1

Correct choice is (a) One of twelve main classes of biochemical reactions

For explanation I would say: Option “One of twelve main classes of biochemical reactions” should be ‘one of six main classes of biochemical reactions’. The Enzyme Commission numbers formulated by the Enzyme Commission of the International Union of Biochemistry and Molecular Biology provide a detailed way to classify enzymes based on the biochemical reactions they catalyze.
