Digestive enzymes responsible for breaking down disaccharides include

Options

A. Pepsin, trypsin and trypsinogen
B. Amylase, pepsin, and lipase
C. Sucrase, lactase, and maltase
D. Pepsin, trypsin and chymotrypsin

Answer

To answer the question about which digestive enzymes are responsible for breaking down disaccharides, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Disaccharides**:
- Disaccharides are carbohydrates composed of two monosaccharide units linked by a glycosidic bond. Common examples include sucrose, lactose, and maltose.

2. **Identifying the Enzymes**:
- Each disaccharide is broken down by specific enzymes:
- **Sucrose** is broken down by the enzyme **sucrase** (or invertase), yielding glucose and fructose.
- **Lactose** is broken down by the enzyme **lactase**, yielding glucose and galactose.
- **Maltose** is broken down by the enzyme **maltase**, yielding two glucose molecules.

3. **Analyzing the Options**:
- The question provides several options:
- a) Pepsin, Trypsin, Trypsinogen
- b) Amylase, Pepsin, Lipase
- c) Sucrase, Lactase, Maltase
- d) Pepsin, Trypsin, Chymotrypsin
- We need to identify which of these options contains the enzymes that specifically break down disaccharides.

4. **Evaluating Each Option**:
- **Option a**: Pepsin, Trypsin, Trypsinogen - These enzymes are involved in protein digestion, not disaccharides.
- **Option b**: Amylase, Pepsin, Lipase - Amylase breaks down starch, while Pepsin and Lipase are for proteins and fats respectively.
- **Option c**: Sucrase, Lactase, Maltase - These enzymes are specifically responsible for breaking down disaccharides into their monosaccharide components.
- **Option d**: Pepsin, Trypsin, Chymotrypsin - Like option a, these are enzymes for protein digestion.

5. **Conclusion**:
- The correct answer is **option c: Sucrase, Lactase, Maltase**, as these are the enzymes responsible for breaking down disaccharides.
