Options

A. proteins
B. carbohydrates
C. fats
D. glucose

Answer

**Step-by-Step Solution:**

1. **Understanding the Source of Bile Juice:**
- Bile juice is secreted by the liver and stored in the gallbladder.

2. **Identifying the Role of Bile Juice:**
- The primary function of bile juice in digestion is to aid in the digestion of fats.

3. **Understanding Emulsification:**
- Bile juice does not contain enzymes but plays a crucial role in the emulsification of fats. Emulsification is the process of breaking down large fat molecules into smaller droplets, which increases the surface area for enzymes to act upon.

4. **The Process of Digestion:**
- In the stomach, the enzyme lipase begins the digestion of fats, but it cannot function effectively due to the low pH. Once the food moves to the small intestine, bile juice is released to emulsify the fats, making them easier for lipase to digest.

5. **Conclusion:**
- Therefore, bile juice is chiefly involved in the digestion of fats.

**Final Answer:**
Bile juice is chiefly involved in the digestion of fats.
