Q.Match column I with column II and choose the correct option
Column – I | Column – II
(P) Lipase |

Step 1. Match P (Lipase) to (iv) Lipid, since lipase is the enzyme that hydrolyses fats/lipids into fatty acids and glycerol.

Step 2. Match Q (Pepsin) to (iii) Protein, since pepsin is the general proteolytic enzyme of the stomach that breaks down proteins into proteoses and peptones.

Step 3. Match R (Renin) to (ii) Cassein [as printed in the source, i.e. casein], since renin (rennin) specifically converts the milk protein caseinogen into casein — a more specific substrate than 'protein' in general, which is why it is paired separately from pepsin. …

Recall each enzyme's specific substrate from the chapter, noting that renin's substrate (casein/caseinogen) is more …

• Pairing renin with the general 'protein' option instead of the more specific 'casein' option meant to distinguish it from pepsin. …
