Which one of the following is a matching pair of substrate and its prticular digestive enzyme?

Options

A. Maltose-Maltase
B. Lactose- Rennin
C. Starch - Steapsin
D. Casein-Chymotrypsin

Explanation

To determine the matching pair of substrate and its particular digestive enzyme, we will analyze each option provided in the question.

**Step 1: Analyze the first pair - Maltose and Maltase**
- Maltose is a disaccharide composed of two glucose molecules. The enzyme maltase specifically hydrolyzes maltose into its monosaccharide components, which are glucose molecules.
- **Conclusion**: This pair is a correct match.

**Step 2: Analyze the second pair - Lactose and Renin**
- Lactose is a disaccharide made up of glucose and galactose. Renin is not a digestive enzyme; it is involved in regulating blood pressure and does not act on lactose.
- **Conclusion**: This pair is an incorrect match.

**Step 3: Analyze the third pair - Starch and Steapsin**
- Starch is a polysaccharide made up of many glucose units. Steapsin (more commonly known as lipase) is an enzyme that digests fats, not starch.
- **Conclusion**: This pair is an incorrect match.

**Step 4: Analyze the fourth pair - Casein and Chymotrypsin**
- Casein is a protein found in milk. Chymotrypsin is a proteolytic enzyme that breaks down proteins, but it does not specifically act on casein.
- **Conclusion**: This pair is an incorrect match.

**Final Conclusion**: The only correct matching pair of substrate and its particular digestive enzyme is **Maltose and Maltase**.
