Question

Which one of the following enzymes requires Molybdenum as the co-factor?

• A. Carboxylase
• B. Hecokinase
• C. Flavin oxidase
• D. Nitrate reeducates

Answer 1

The correct option is D Nitrate reeducates

Molybdenum has a versatile redox chemistry that is used by the enzymes to catalyze diverse redox reactions. Molybdenum enzymes generally catalyze the transfer of an oxygen atom. The trace element molybdenum is essential for nearly all organisms and forms the catalytic centre of a large variety of enzymes such as nitrate reductases.

So, the correct option is 'D'.
