NEET 2026 (Phase 1) · BiologyCell compositionPrevious Year Question
Identify the correct statements about biomolecules. A. Lipids are generally water soluble. B. Proteins are polypeptides. C. Polysaccharides are long chains of sugars. D. Adenine and guanine are substituted pyrimidines. E. Almost all enzymes are proteins. Choose the correct answer from the options given below:
Answer: (B) B, C and E only. Answer: (B) B, C and E only.
- A.B, D and E only
- B.B, C and E only✓
- C.A, B and C only
- D.C, D and E only
Correct Answer
(B) B, C and E only
Solution & Explanation
Answer: (B) B, C and E only. Solution: Statement A is wrong because NCERT states lipids are generally water insoluble, not soluble. Statement D is wrong because adenine and guanine are substituted purines, not pyrimidines. Statements B (proteins are polypeptides), C (polysaccharides are long chains of sugars) and E (almost all enzymes are proteins) are all directly stated in NCERT, so B, C and E only are correct. NCERT Reference: Ch 9, p.111, line ~21 — "Adenine and Guanine are substituted purines while the rest are substituted pyrimidines."
