Match the biochemical process in List I with the corresponding catalyst in List II. List I: (P) Hydrolysis of cane sugar (sucrose) (Q) Conversion of starch to maltose (R) Conversion of glucose to ethyl alcohol (S) Conversion of milk to curd List II: (1) Diastase (2) Lactobacillus enzyme (3) Invertase (4) Zymase

1. P -> 3; Q -> 4; R -> 1; S -> 2
2. P -> 3; Q -> 4; R -> 2; S -> 1
3. P -> 3; Q -> 1; R -> 4; S -> 2
4. P -> 2; Q -> 4; R -> 1; S -> 2

Correct answer: P -> 3; Q -> 1; R -> 4; S -> 2

Solution

P (sucrose hydrolysis) -> Invertase = (3). Q (starch -> maltose) -> Diastase = (1). R (glucose -> ethanol) -> Zymase = (4). S (milk -> curd) -> Lactobacillus enzyme = (2).
