2. NEET 2026MediumBiomacromolecules
   Q2

   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:

   • AB, D and E only
   • BB, C and E only
   • CA, B and C only
   • DC, D and E only

   Show answer & solution

   Correct answer: (B)

   A false (lipids are insoluble). B true. C true. D false (they are purines). E true. So B, C, E.
3. NEET 2026HardEnzymes
   Q3

   Match List I with List II:
   
   List I (Bioactive molecules):
   
   A. Streptokinase,
   
   B. Statins,
   
   C. Lipases,
   
   D. Cyclosporin A
   
   List II (Importance):
   
   I. Immunosuppressive agent,
   
   II. Removal of clots from the blood vessels,
   
   III. Blood cholesterol-lowering agent,
   
   IV. Detergent formulations
   
   Choose the correct answer from the options given below:

   • AA-II, B-III, C-I, D-IV
   • BA-IV, B-III, C-II, D-I
   • CA-III, B-II, C-IV, D-I
   • DA-II, B-III, C-IV, D-I

   Show answer & solution

   Correct answer: (D)

   Streptokinase -- clot buster (II); Statins -- cholesterol lowering (III); Lipases -- detergents (IV); Cyclosporin A -- immunosuppressant
   
   (I). So A-II, B-III, C-IV, D-I.
