Question

A phenomenon in degradation process wherein an intermediate product of herbicides proves more phytotoxic than the parent compound is:

• A. Reverse metabolism
• B. Conjugation
• C. Metabolism
• D. Coupling

Hint:

Reverse metabolism: intermediate is more toxic.
Conjugation: detoxification process.
Metabolism: breakdown of herbicides.

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
Herbicide degradation can produce intermediates.
Some intermediates may be more toxic than the parent.

Step 2: Key Formula or Approach:
No specific formula.
Need to know the degradation processes.

Step 3: Detailed Explanation:
Reverse metabolism is the phenomenon where an intermediate product is more phytotoxic than the parent compound.
Conjugation is the attachment of a molecule to the herbicide.
Metabolism is the general breakdown process.
Coupling is the joining of molecules.
Thus, reverse metabolism is the correct term.

Step 4: Final Answer:
The phenomenon is called reverse metabolism.
Hence, the correct option is (A).
