Bile comprises of

Options

A. Three types of enzymes
B. 10 types of enzymes
C. Only one type of enzyme
D. No digestive enzymes

Answer

### Step-by-Step Text Solution:

1. **Understanding Bile**: Bile is a digestive fluid produced by the liver and stored in the gallbladder. It plays a crucial role in the digestion of fats.

2. **Composition of Bile**: Bile is composed of several components:
- **Bile Pigments**: These include bilirubin and biliverdin, which are products of the breakdown of hemoglobin.
- **Bile Salts**: These are derived from cholesterol and are essential for the emulsification of fats.
- **Cholesterol**: A type of lipid that is also a component of bile.
- **Phospholipids**: These are molecules that help in the emulsification process.

3. **Absence of Digestive Enzymes**: It is important to note that bile does not contain any digestive enzymes. Instead, its primary function is to aid in the emulsification of fats, which increases the surface area for lipase (a digestive enzyme) to act upon.

4. **Function of Bile**: The emulsification process breaks down large fat globules into smaller micelles, making it easier for lipase to digest fats effectively.

5. **Conclusion**: Given the composition of bile, the correct answer to the question "Bile comprises of" is **D: no digestive enzyme**.
