Which ofthe following cannot be digested by pancreatic enzymes

Options

A. proteins
B. starch
C. fats
D. vitamins

Answer

To determine which of the following cannot be digested by pancreatic enzymes, we will analyze each option provided:

1. **Understanding Pancreatic Enzymes**: The pancreas releases pancreatic juice, which contains several enzymes that aid in digestion. The key enzymes include:
- **Proteases** (like trypsin and chymotrypsin) for protein digestion.
- **Amylase** for carbohydrate (starch) digestion.
- **Lipase** for fat digestion.
- **Nucleases** for nucleic acid digestion.

2. **Analyzing Each Option**:
- **A. Proteins**: Digested by proteases (trypsin, chymotrypsin).
- **B. Starch**: Digested by amylase.
- **C. Fats**: Digested by lipase.
- **D. Vitamins**: Vitamins are already in a simple form and do not require digestion. They are absorbed directly into the bloodstream.

3. **Conclusion**: Among the options, vitamins are the only substances that cannot be digested by pancreatic enzymes because they do not need to be broken down further; they are absorbed in their existing form.

Thus, the answer is **D. Vitamins**.
