Question

For its activity, nitrogenease requires

• A. Light
• B. Manganese
• C. Super oxygen radicals
• D. High input of energy

Answer 1

The correct option is D High input of energy

Nitrogenases are enzymes that are produced by certain bacteria and help in the reduction of nitrogen gas to ammonia. This reaction is a key step in the process of nitrogen fixation. This reaction has a very high activation energy and hence, requires a huge amount of energy input.

So, the correct answer is 'High input of energy'.
