Which of the following are incorrectly matched?

Options

A. Protein-trypsin
B. Starch-amylase
C. Fat-lipase
D. Maltose-pepsin

Answer

To determine which of the following options are incorrectly matched, we will analyze each option one by one.

### Step-by-Step Solution:

1. **Analyze Option 1: Protein and Trypsin**
- Trypsin is an enzyme that digests proteins. It is secreted in an inactive form (trypsinogen) and is activated in the small intestine.
- Conclusion: This option is correctly matched.

2. **Analyze Option 2: Starch and Amylase**
- Starch is a polysaccharide, and the enzyme amylase is responsible for breaking down starch into simpler sugars (disaccharides).
- Conclusion: This option is correctly matched.

3. **Analyze Option 3: Fat and Lipase**
- Lipase is the enzyme that breaks down fats into fatty acids and glycerol (monoglycerides).
- Conclusion: This option is correctly matched.

4. **Analyze Option 4: Trypsin and Maltose**
- Maltose is a disaccharide, and trypsin is a protein-digesting enzyme. Trypsin does not act on carbohydrates like maltose.
- Conclusion: This option is incorrectly matched.

### Final Answer:
Only option 4 is incorrectly matched.
