Match Column I , II and III
Column I (metal)Column II (enzyme)Column III (end product)
A Nii Carbonic anhydraseX uric acid
B Znii Xanthine oxidaseY methane
C Moiii Coenzyme $\mathrm{F_{430}}$Z carbonic acid
The correct match is
(a)A-iii-Y, B-i-Z ,C-ii-X
(b)A-iii-Y, B-ii-X, C-i-Z
(c)A-ii-X, B-i-Y, C-iii-Z
(d)A-i-X, B-iii-Z, C-ii-Y
Answer
SELF-PRACTICE — the source book printed no answer.

Nothing is invented here, so this question has no answer on record.

Explanation
(A) Ni present in coenzyme $\mathrm{F_{430}}$ (III) which catalyzes the release of methane (Y) in the final step of methanogenesis. (B) Zn present in carbonic anhydrase (I) which catalyses the hydration of $\mathrm{CO_2}$ into $\mathrm{H_2CO_3}$ (Z). (C) Mo present in Xanthine oxidase (II) which catalyzes the oxidation of Xanthine to uric acid (X).
