Carboxypeptidase is secreted by

Options

A. Pancreas
B. Stomach
C. Salivary glands
D. Intestine

Answer

**Step-by-Step Solution:**

1. **Understanding Carboxypeptidase**: Carboxypeptidase is an enzyme that plays a crucial role in protein digestion. It helps in the hydrolysis of proteins into smaller peptides and amino acids.

2. **Identifying the Source of Carboxypeptidase**: To determine where carboxypeptidase is secreted from, we need to examine the options provided: pancreas, stomach, salivary gland, and intestine.

3. **Analyzing Each Option**:
- **Pancreas**: The pancreas produces pancreatic juice, which contains several digestive enzymes, including carboxypeptidase, trypsin, and chymotrypsin. This makes the pancreas a strong candidate for the source of carboxypeptidase.
- **Stomach**: The stomach secretes gastric juice, which contains hydrochloric acid (HCl), mucus, and pepsin. Pepsin is involved in protein digestion but does not include carboxypeptidase.
- **Salivary Gland**: Salivary glands produce saliva, which primarily contains salivary amylase, an enzyme that digests carbohydrates. They do not secrete carboxypeptidase.
- **Intestine**: The intestine secretes intestinal juice, which contains various enzymes like sucrase and maltase, but it does not include carboxypeptidase.

4. **Conclusion**: Based on the analysis, carboxypeptidase is secreted by the pancreas, making it the correct answer.

**Final Answer**: Carboxypeptidase is secreted by the pancreas.
