Day 7

Spaced Revision

Come back to Nitrogen Metabolism after a week. Use flashcards for quick recall and try past exam questions on this chapter.

What to Focus On

  • The nitrogen cycle has five key steps.
  • It involves both abiotic (non-living) and biotic (living) components.
  • Microorganisms play a major role in converting nitrogen into usable forms.
  • Nitrogen fixation converts N₂ into NH₃.
  • Abiological fixation occurs via lightning and industrial Haber’s process.
  • Biological fixation is done by microbes using nitrogenase enzyme.
  • Free-living fixers: Azotobacter, Clostridium, Klebsiella.
  • Symbiotic fixers: Rhizobium (legumes), Azospirillum (grasses), Cyanobacteria (water bodies).
  • Root nodules provide ideal conditions for nitrogen fixation.

Common Mistakes to Avoid

Plants can directly absorb atmospheric nitrogen (N₂) from the air through their leaves or roots.

Nitrification means converting nitrogen gas into nitrates.

Denitrification is beneficial for plant growth because it adds nitrates to the soil.

Memory Tips

Five steps of the nitrogen cycle: Nitrogen Fixation, Assimilation, Ammonification, Nitrification, Denitrification

Biological nitrogen fixation is done by microbes like Rhizobium, Azotobacter, Clostridium, and Cyanobacteria

Nitrogenase enzyme requires Mo-Fe and is oxygen-sensitive

Reductive amination: Ammonia + α-ketoglutaric acid → Glutamate
