Question

Match the enzymes in Group I with the reactions in Group II. Select the correct combination.

Group I	Group II
P. Hydrolase	i. Inter-conversion of optical isomers
P. Hydrolase	ii. Oxidation and reduction of two substrates
R. Isomeras	iii. Joining of two compounds
S. Ligase	iv. Removal of a chemical group from a substrate
	v. Transfer of a chemical group from one substrate to another

(A) P-iv, Q-ii, R-iii, S-i 

(B) P-v, Q-iv, R-i, S-iii 

(C) P-iv, Q-i, R-iii, S-v 

(D) P-i, Q-iv, R-v, S-ii 

Answer 1

Correct Option :- (B) P-v, Q-iv, R-i, S-iii

Explanation :-

(i) Hydrolase catalyses hydrolysis of ester, ether, peptide, glycosidic, C–C, C-halide or P–N bonds 

(ii) Lyase catalyses removal of groups other than hydrolysis 

(iii) Isomerase catalyses interconversion of optical, geometric or positional isomers. 

(iv) Ligase catalyses linking together of two compounds
