Study the following statement and choose the correct answer
i) Neutral fats are stored in the adipose tissue and liver
ii) Small protein coated fat globules called chylomicrons are transported into lacteals by exocytosis
iii) Peristaltic movements of intestine are fast and help in the transport of nutrients into the ileum
(iv) Calorific value of 1 gm of fat and 1 gm of carbohydrates put together

Options

A. I and ii
B. ii and iii
C. I and iv
D. ii and iv

Answer

To solve the question, we need to analyze each statement provided and determine its correctness based on our understanding of digestion and absorption.

### Step-by-Step Solution:

1. **Statement i: Neutral fats are stored in the adipose tissue and liver.**
- **Analysis:** Neutral fats, also known as triglycerides, are indeed stored in adipose tissue, which is specialized for fat storage. The liver can also store excess fat, which can be utilized for energy when needed.
- **Conclusion:** This statement is **correct**.

2. **Statement ii: Small protein-coated fat globules called chylomicrons are transported into lacteals by exocytosis.**
- **Analysis:** Chylomicrons are indeed small lipoprotein particles that transport dietary lipids from the intestines to other locations in the body. They are formed in the intestinal epithelial cells and enter the lymphatic system via lacteals through the process of exocytosis.
- **Conclusion:** This statement is **correct**.

3. **Statement iii: Peristaltic movements of the intestine are fast and help in the transport of nutrients into the ileum.**
- **Analysis:** Peristalsis refers to the wave-like muscle contractions that move food through the digestive tract. While peristaltic movements do occur in the intestine, their primary role is to mix and propel food rather than to rapidly transport nutrients. The absorption of nutrients occurs primarily in the small intestine, particularly in the ileum, but peristalsis itself is not characterized as "fast."
- **Conclusion:** This statement is **incorrect**.

4. **Statement iv: Calorific value of 1 gm of fat and 1 gm of carbohydrates put together.**
- **Analysis:** The calorific value of fat is approximately 9 calories per gram, while carbohydrates provide about 4 calories per gram. If we consider them together, the total calorific value would be 9 + 4 = 13 calories. However, the statement is vague and does not specify what is meant by "put together."
- **Conclusion:** This statement is somewhat ambiguous, but it does not provide a clear correct or incorrect assertion.

### Final Answer:
Based on the analysis:
- **Correct Statements:** i and ii
- **Incorrect Statements:** iii
- **Ambiguous Statement:** iv

Therefore, the correct answer would be that statements i and ii are correct.
