This task requires matching enzymes from List I with the bond types they act upon from List II. The correct pairings are as follows:
| List I (Enzymes) | List II (Bond Types) |
| A. Lipase | II. Ester bond |
| B. Nuclease | IV. Phosphodiester bond |
| C. Protease | I. Peptide bond |
| D. Amylase | III. Glycosidic bond |
The specific relationships are:
- Lipase catalyzes the hydrolysis of ester bonds.
- Nuclease cleaves phosphodiester bonds.
- Protease breaks peptide bonds.
- Amylase hydrolyzes glycosidic bonds.
The correct match is A-II, B-IV, C-I, D-III.
