Question

Ammonia produced following nitrogen fixation is incorporated into amino acids as the?

• A. Amino group
• B. Keto group
• C. Carboxyl group
• D. Hydroxyl group

Answer 1

The correct option is A Amino group

Nitrogen fixation is the process of conversion of inert atmospheric nitrogen into utilisation compounds of nitrogen like nitrate, ammonia, etc. Conversion of ammonia generated from nitrate assimilation or photorespiration into amino acid via primary and alternative pathways. Ammonia is then incorporated into amino acids as amino group and help in the assimilation of nitrogen.

So the correct answer is 'Amino group'.
