Which of the following statements is incorrect in relation to leghaemoglobin?
Options
- ALeghaemoglobin functions as oxygen scavenger.
- BIt is synthesized by host cell.
- CIt makes nodules pink coloured.
- DIt oxidizes enzyme nitrogenase.
Correct answer
D. It oxidizes enzyme nitrogenase.
Step-by-step solution
The enzyme nitrogenase which carries out nitrogen fixation is highly sensitive to molecular oxygen and it requires anaerobic conditions. To protect this enzyme, the nodule contains an oxygen scavenger called leghemoglobin, which is synthesized by host cell and is pinkish coloured substance.
