Enzymes

The correct answer is (C): A-IV, B-III, C-I, D-II

1. Invertase → Cane sugar into glucose
2. Zymase → Glucose into ethanol
3. Diastase → Starch into maltose
4. Maltase → Maltose into glucose

To determine the incorrect statements regarding enzymes, let's evaluate each statement:

1. Statement A: Enzymes are biocatalysts.
   This statement is correct. Enzymes are biological catalysts that speed up chemical reactions in living organisms without being consumed in the process.
2. Statement B: Enzymes are non-specific and can catalyse different kinds of reactions.
   This statement is incorrect. Enzymes are highly specific, meaning each enzyme typically catalyses only one particular type of reaction or acts on a specific substrate due to the unique shape of its active site.
3. Statement C: Most Enzymes are globular proteins.
   This statement is correct. Enzymes are mainly composed of globular proteins that have complex three-dimensional structures essential for their catalytic activities.
4. Statement D: Enzyme - oxidase catalyses the hydrolysis of maltose into glucose.
   This statement is incorrect. Oxidases are enzymes that catalyse oxidation-reduction reactions, not hydrolysis. The enzyme that catalyses the hydrolysis of maltose into glucose is maltase, not oxidase.

Based on the evaluation above, the incorrect statements are (B) and (D).
Therefore, the correct answer is: (B) and (D)
