Pancreatic juice digests
(a) only carbohydrates
(b) carbohydrates and proteins
(c) carbohydrates, proteins and lipids
(d) only proteins

Options

A. only carbohydrates
B. carbohydrates and proteins
C. carbohydrates, proteins and lipids
D. only proteins

Explanation

To answer the question about what pancreatic juice digests, we can break down the information step by step:

### Step-by-Step Solution:

1. **Identify the Source of Pancreatic Juice**:
- Pancreatic juice is secreted by the pancreas, an important organ in the digestive system.

2. **Understand the Nature of Pancreatic Juice**:
- It is an alkaline secretion, which helps neutralize stomach acid and provides an optimal environment for digestive enzymes to function.

3. **Volume of Pancreatic Juice**:
- The pancreas secretes approximately 200-800 ml of pancreatic juice per day.

4. **Identify the Enzymes in Pancreatic Juice**:
- The pancreatic juice contains several key enzymes:
- **Amylase**: Digests carbohydrates by breaking them down into simpler sugars.
- **Trypsin**: Digests proteins by breaking them down into smaller peptides.
- **Lipase**: Digests lipids (fats) by breaking them down into fatty acids and glycerol.

5. **Determine the Substrates Digested by Pancreatic Juice**:
- Given the presence of amylase, trypsin, and lipase, pancreatic juice is capable of digesting:
- Carbohydrates (by amylase)
- Proteins (by trypsin)
- Lipids (by lipase)

6. **Conclusion**:
- Therefore, pancreatic juice digests carbohydrates, proteins, and lipids. The correct answer is option (c) carbohydrates, proteins, and lipids.

### Final Answer:
(c) carbohydrates, proteins and lipids
