The chief function of bile is to `:`

Options

A. Digest fat by enzymatic action
B. Emulsify fats for digestion
C. Eliminate waste products
D. Regulate digestion of proteins

Answer

**Step-by-Step Solution:**

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

2. **Function of Bile:**
- The primary function of bile is to aid in the emulsification of fats. Emulsification refers to the process of breaking down large fat globules into smaller droplets, which increases the surface area for enzymes to act upon.

3. **Emulsification Process:**
- When bile is released into the small intestine, it helps to emulsify dietary fats. This means that the fat molecules are broken down into smaller particles, known as micelles. This process is essential for the efficient digestion and absorption of fats.

4. **Activation of Enzymes:**
- Bile also plays a role in activating the lipase enzyme, which is responsible for breaking down fats into fatty acids and glycerol. This enzymatic action is crucial for the digestion of fats.

5. **Evaluating Options:**
- Given the options:
- A. Digestion of fats by enzymatic action (Incorrect)
- B. Emulsify fat for digestion (Correct)
- C. Eliminate waste products (Incorrect)
- D. Regulate digestion of protein (Incorrect)
- The correct answer is option B, as it directly states the chief function of bile.

**Final Answer:**
The chief function of bile is to emulsify fat for digestion.
