Enzyme trypsinogen is a component of

Options

A. Mucus
B. Saliva
C. Pancreatic juice
D. Intestinal juice

Answer

**Step-by-Step Solution:**

1. **Understanding Trypsinogen**: Trypsinogen is an inactive form of the enzyme trypsin. It is important to note that it is not active until it is converted into trypsin.

2. **Source of Trypsinogen**: Trypsinogen is secreted by the pancreas. The pancreas functions as both an endocrine and exocrine gland.

3. **Function of Trypsinogen**: Trypsinogen is classified as a protease, which means it is involved in breaking down proteins. However, in its inactive form, it does not perform this function until it is activated.

4. **Activation of Trypsinogen**: The enzyme enterokinase activates trypsinogen by converting it into trypsin. Once activated, trypsin can then break down proteins into smaller peptides.

5. **Pancreatic Juice**: Since trypsinogen is secreted by the pancreas, it is a component of pancreatic juice. Pancreatic juice contains various digestive enzymes, including trypsinogen.

6. **Conclusion**: Among the options provided (mucus, saliva, pancreatic juice, and intestinal juice), the correct answer is pancreatic juice, as it is the only one that contains trypsinogen.

**Final Answer**: Trypsinogen is a component of pancreatic juice.
