Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Concept
Secondary metabolites are grouped by their chemical structures and biosynthetic pathways.
Step 2: Meaning
Terpenoids are made of isoprene units (C5H8), and flavonoids are polyphenolic compounds; neither requires Nitrogen.
Step 3: Analysis
Alkaloids are a large group of naturally occurring chemical compounds that contain mostly basic nitrogen atoms. Examples include caffeine, morphine, and nicotine.
Step 4: Conclusion
Alkaloids are the primary class of nitrogen-containing secondary metabolites in plants. Final Answer: (C)
