← Nature & AnimalsWhich consequence results when a legume's nitrogen fixation nodules face oxygen deprivation?
A)Ammonia diffusion shifts from roots
B)Nitrogenase effectiveness decreases significantly✓
C)Leghemoglobin transports surplus oxygen
D)Nodule ATP synthesis rate accelerates
💡 Explanation
When oxygen-deprived, root nodules implementing nitrogen fixation experience inhibited nitrogenase activity because nitrogenase is highly sensitive to oxygen, therefore less ammonia get synthesized rather than more due to ATP synthesis slowing due to anaerobic conditions.
