Question

In plants, atmospheric nitrogen is converted into :

• A. carbohydrate
• B. proteins
• C. amino acids
• D. fats

Answer 1

Answer: (B), (C)

proteins
amino acids

Nitrogen fixation is a process in which nitrogen ($N_2$) in the atmosphere is converted into ammonium ($N{H}_4^{+}$). Nitrogen fixation, natural and synthetic, is essential for all forms of life because nitrogen is required to biosynthesize basic building blocks of plants, animals and other life forms, e.g., nucleotides for DNA and RNA and amino acids for proteins.
