Question

Match the enzymes in column I with their respective biochemical reactions in column II. Choose the correct combination from.

Column I	Column II
(P) Transaminases acid	(i) removal of phosphoryl group from a specific amino
(Q) Protein Kinases acid	(ii) removal of $\alpha$-amino group from a specific amino
(R) Protein Phosphatases acid	(iii) addition of phosphoryl group to a specific amino
(S) Dehydrogenases	(iv) interconversion of optical isomers
	(v) oxidation and reduction of substrates

• A. P-iv, Q-ii, R-iii, S-v
• B. P-ii, Q-i, R-ii, S-iv
• C. P-ii, Q-iii, R-i, S-v
• D. P-v, Q-ii, R-iii, S-i

Answer 1

The correct option is C P-ii, Q-iii, R-i, S-v

Transaminase enzyme is also called as aminotransferases. It catalyze the removal of an α-amino group from a specific amino acid and transfer it to an α-ketoacid. Protein kinase enzyme carries out phosphorylation process. It catalyzes the addition of phosphoryl group to a specific amino acid.Protein Phosphatases enzyme carries out opposite action to that of protein kinase. It catralyzes the removal of phosphoryl group from a specific amino acid. Dehydrogenase enzyme belongs to the group of oxidoreductases. It carries out oxidation of a substrate by reducing an electron acceptor like NAD, FAD.

Thus, the correct answer is option C.
