Question

Match the Column-I & Column-II Column I Column II

A) ${\mathrm{MoO}}_2^{2+}$	1) Alcoholic dehydrogenase
B) ${\mathrm{Mg}}^{2+}$	2) Nitrogenase
C) ${\mathrm{Zn}}^{2+}$	3) Catalase
D) ${\mathrm{Fe}}^{3+}$	4) PEP carboxylase

• A. A-2, B-4, C-3, D-1
• B. A-2, B-1, C-4, D-3
• C. A-4, B-2, C-1, D-3
• D. A-2, B-4, C-1, D-3

Answer 1

The correct option is D A-2, B-4, C-1, D-3

${\mathrm{MoO}}_2^{2+}$- Nitrogenase
${\mathrm{Mg}}^{2+}$- PEP Carboxylase
${\mathrm{Zn}}^{2+}$- Alcohol dehydrogenase
${\mathrm{Fe}}^{3+}$- Catalase

These are all ions necessary for the functioning of the corresponding enzyme.
