Choose the wrong statement

Options

A. Lipases and nucleases are not present in pancreatic juice
B. Goblet cells secrete mucus
C. Brunner’s glands are sub-mucosal glands
D. Carboxypeptidase catalyses conversion of proteins, peptones and proteoses to dipeptides

Explanation

To solve the question "Choose the wrong statement," we need to analyze each of the provided options regarding their accuracy in relation to digestion and absorption.

### Step-by-Step Solution:

1. **Analyze Option A**: "Lipases and nucleases are not present in pancreatic juice."
- **Explanation**: This statement is incorrect. Pancreatic juice contains various enzymes, including lipases (which digest fats) and nucleases (which digest nucleic acids). Therefore, this statement is false.

2. **Analyze Option B**: "Goblet cells secrete mucus."
- **Explanation**: This statement is correct. Goblet cells are specialized epithelial cells that secrete mucus, which helps lubricate and protect the lining of the gastrointestinal tract.

3. **Analyze Option C**: "Brunner's gland are submucosal glands."
- **Explanation**: This statement is also correct. Brunner's glands are located in the submucosa of the duodenum and secrete alkaline mucus to neutralize gastric acid.

4. **Analyze Option D**: "Carboxypeptidase catalyzes conversion of proteins, peptones, and proteoses to dipeptides."
- **Explanation**: This statement is correct. Carboxypeptidase is an enzyme that breaks down proteins into smaller peptides and ultimately into amino acids or dipeptides.

### Conclusion:
The wrong statement among the options is **Option A**: "Lipases and nucleases are not present in pancreatic juice."

### Final Answer:
**Option A** is the wrong statement.
