Does Rhizobium require anaerobic conditions to fix nitrogen?

Yes

 

[GCE As and a level]

what enzymes in nitrogen cycle requires aerobic conditions and what enzymes in nitrogen cycle requires anaerobic conditions?

 

[Mohammed salik]

what enzymes in nitrogen cycle requires aerobic conditions and what enzymes in nitrogen cycle requires anaerobic conditions?

Nitrification = Aerobic
Nitrogen fixation=Both
Denitrification=Anaerobic

Nitrification = Aerobic
Nitrogen fixation=Both
Denitrification=Anaerobic

Thank u
so u mean that all the enzymes involved in nitrification are aerobic??

Hey. *Just confused here*. There was this MCQ in one of the 2013 papers and the correct answer there was nitrogen-fixation is aerobic. Can you give some examples that prove how this process is both aerobic and anaerobic? (This CIE mark scheme did baffle me because the enzyme nitrogenase requires anaerobic conditions to process, but then I did an internet search and it revealed that leg-hemoglobin won't remove any oxygen if there's no oxygen available, hence turning aerobic conditions to anaerobic).

Look while in Nodules The condition required is Anaerobic while in Soil its Aerobic! let me find out that paper.. then i would let You Know!

What is ammonification and decomposition ? there isnt any difference right?

Yes if You read carefully that question Sai Soil conditions so yea Ans Would Be A..
aerobic for Nitrogen fixation in sil
aerobic Nitrification
anaerobic denitrification
Need any more Help?

Ammonification is Prodution of Ammonium Ions specifically!
Decomposition is just for Break down into simpler substances !

simpler substance like what ?

then what is Assimilation ?

ALLAH! I missed reading the question carefully. Again. -.-
Thanks anyway.

 

[Mohammed salik]

I meant Decomposition Products may Or may not include ammonia.. For example if you Decompose Urea breaks down into Ammonia..!
Assimilation is use of That substance like Nitrates are used to make aminoacids !

Decomposition is the breakdown of polysaccharides and proteins into constituent elements. Like glucose, NH3 wagaira wagaira.
