Study Notes
Nitrogen Cycle
- The organism that plays a critical role in the arrival of oxygen-based metabolism is Cyanobacteria.
- Denitrification is the main biological process of forming N2 from nitrate.
- The atmosphere is a major reservoir of N2.
- Ammonia (NH3) is the first stable product of nitrogen fixation.
- Anabaena, a micro-organism, is sensitive to oxygen and evolves to solve the problem by forming heterocysts.
- Nitrification involves the oxidation of NH4+ to NO3-.
- The main energy source for nitrogenase during nitrogen fixation in symbiotic plants is ATP.
- Nitrosomonas and Nitrobacter are the bacteria involved in the process of nitrification.
- The end product of the anammox process is N2.
- Ammonification involves the release of NH4+ from organic nitrogen.
- The ozone layer plays a crucial role in the context of the nitrogen cycle by protecting nitrogen-fixing organisms from UV radiation.
