Match List I with List II regarding enzymes and the type of bond they hydrolyse.
Column I
- A. Lipase
- B. Nuclease
- C. Protease
- D. Amylase
Column II
- I. Peptide bond
- II. Ester bond
- III. Glycosidic bond
- IV. Phosphodiester bond
Correct answer: A → II, B → IV, C → I, D → III
Solution
Lipase – hydrolyses ester bonds in lipids
Nuclease – hydrolyses phosphodiester bonds in nucleic acids
Protease – hydrolyses peptide bonds in proteins
Amylase – hydrolyses glycosidic bonds in carbohydrates (starch)
Correct match: A-II, B-IV, C-I, D-III.
Concept
Matching lipase, nuclease, protease, amylase to ester/phosphodiester/peptide/glycosidic bonds
