NEET 2023 Phase 2 · BiologyCell compositionPrevious Year Question
Which of the following is not a secondary metabolite?
Answer: (B) Lecithin. Answer: (B) Lecithin.
- A.Anthocyanin
- B.Lecithin✓
- C.Curcumin
- D.Morphine
Correct Answer
(B) Lecithin
Solution & Explanation
Answer: (B) Lecithin. Solution: Lecithin is a phospholipid (a primary-metabolite lipid of cell membranes), not a secondary metabolite. Anthocyanin is a pigment, curcumin is a drug, and morphine is an alkaloid, all of which appear among the listed secondary metabolites, so lecithin is the odd one out. NCERT Reference: Ch 9, p.106, line ~28 — "These are phospholipids. They are found in cell membrane. Lecithin is one example."
