Question

Given below are two statements
Statement I: Enzymatic digestion of protein and proteinous compounds by non-specific heterotrophic microbes is amination process.
Statement II: Enzymatic conversion of ammonia to amino acid is ammonification process.
Ammonification process is carried out by both aerobic and anaerobic microorganisms.
In light of the above statements, choose the most appropriate answer from the options given below:

• A. Both Statement I and Statement II are correct
• B. Both Statement I and Statement II are incorrect
• C. Statement I is correct but Statement II is incorrect
• D. Statement I is incorrect but Statement II is correct

Hint:

Nitrogen transformations:
- Amination: Ammonia to amino acids.
- Ammonification: Organic N to NH3/NH4+.
- Nitrification: NH4+ to NO3-.
- Denitrification: NO3- to N2.

Answer 1

The Correct Option is D

Step 1: Understanding the Concept:
Nitrogen transformation in soil involves two important biological processes: ammonification and amination. These processes are carried out by microorganisms during the decomposition and synthesis of nitrogenous compounds.

Step 2: Explanation of the Statements:
Statement I: Enzymatic digestion of proteins by non-specific heterotrophic microorganisms is called amination. This statement is incorrect because the breakdown of proteins into ammonia is known as ammonification. Statement II: Ammonification is associated with microbial conversion of organic nitrogen and is performed by both aerobic and anaerobic microorganisms. Hence, this statement is considered correct in the given context.

Step 3: Final Answer:
Therefore, Statement I is incorrect but Statement II is correct.} Hence, the correct option is (D).
