1. Which of the following saturated fats does not contain cholesterol?

Correct answer: B

Rationale: The correct answer is B, Coconut oil. Coconut oil is a saturated fat derived from plants and does not contain cholesterol, unlike the other options. Butter (choice A) is an animal-derived saturated fat that contains cholesterol. Eggs (choice C) and fish (choice D) also contain cholesterol, making them incorrect choices. Therefore, coconut oil is the only option that is a saturated fat and does not contain cholesterol.

2. The type of protein-energy malnutrition (PEM) that develops when the diet lacks protein is called:

Correct answer: A

Rationale: The correct answer is A: kwashiorkor. Kwashiorkor is a form of protein-energy malnutrition that arises due to a protein-deficient diet. This condition leads to symptoms such as edema, skin lesions, and fatty liver. Choice B, marasmus, is a form of PEM caused by overall malnutrition (protein and calorie deficiency), resulting in severe wasting and muscle loss. Choice C, anemia, is a condition characterized by a deficiency of red blood cells or hemoglobin, not specifically related to protein deficiency. Choice D, beriberi, is a disease caused by thiamine (Vitamin B1) deficiency, not a form of PEM related to protein deficiency.

3. Which of the following is an example of a disaccharide?

Correct answer: D

Rationale: The correct answer is D, Maltose. A disaccharide is formed when two monosaccharides are joined together. Glucose, fructose, and galactose are all monosaccharides, not disaccharides. Therefore, they are not examples of disaccharides.

4. What are the small, fingerlike projections into the intestinal lumen called?

Correct answer: A

Rationale: The correct answer is A: Villi. Villi are small fingerlike projections in the intestine that increase the surface area for nutrient absorption. Goblets (choice B) are mucus-secreting cells in the intestines. Lacteals (choice C) are lymphatic vessels in the small intestine that absorb dietary fats. Polyps (choice D) are abnormal tissue growths.

5. How is resistant starch digested in the colon?

Correct answer: A

Rationale: In the colon, resistant starch is digested by bacterial fermentation. The correct answer is A. During this process, short-chain fatty acids are produced. Pancreatic amylase, as mentioned in choice B, is responsible for breaking down starch in the small intestine, not in the colon. Choice C, hydrochloric acid, functions in the stomach to aid in the digestion of proteins, not starch. Villi and microvilli, as stated in choice D, are structures in the small intestine that absorb nutrients; they do not participate in the digestion of resistant starch in the colon.
