Bile comprises

Options

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

Answer

**Step-by-Step 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 and absorption of fats.

2. **Function of Bile:** The primary function of bile is the emulsification of fats, which means it breaks down large fat globules into smaller droplets, making it easier for enzymes to digest them.

3. **Composition of Bile:** Bile is composed of several components:
- **Water:** The major component, constituting about 97-98% of bile.
- **Bile Salts:** These are derived from cholesterol and help in the emulsification of fats. They make up around 0.7% of bile and include sodium glycolate and sodium taurocolate.
- **Bile Pigments:** These include bilirubin and biliverdin, which are responsible for the color of bile. They constitute about 0.2% of bile.
- **Fats:** Bile also contains a small amount of fats (around 0.5%), which include cholesterol, fatty acids, and lecithin.

4. **Presence of Enzymes in Bile:** It is important to note that bile does not contain enzymes. Instead, it contains bile salts that assist in fat digestion but do not act as enzymes themselves.

5. **Conclusion:** Given the options provided in the question:
- Three types of enzymes
- Ten types of enzymes
- Only one type of enzyme
- No enzymes

The correct answer is "no enzymes" since bile does not contain any enzymes.

**Final Answer:** Bile comprises no enzymes.
