1. Which is NOT a classification of carbohydrate?

• A. Monosaccharides
• B. Disaccharides
• C. Polysaccharides
• D. Triglycerides

Correct answer: D

Rationale: The correct answer is D, Triglycerides. Triglycerides are a type of fat, not a carbohydrate. Monosaccharides, disaccharides, and polysaccharides are all classifications of carbohydrates based on the number of sugar units they contain. Monosaccharides are the simplest form with one sugar unit, disaccharides contain two sugar units, and polysaccharides have multiple sugar units linked together.

2. What is the end product of lipid digestion?

• A. fatty acid
• B. sucrose
• C. monosaccharide
• D. amino acid

Correct answer: A

Rationale: The correct answer is A, fatty acid. During the process of lipid digestion, triglycerides are broken down into fatty acids and glycerol. These end products are then absorbed into the bloodstream or lymphatic system for further processing. Choices B, C, and D are incorrect because sucrose is a disaccharide, monosaccharide is a simple sugar unit, and amino acid is a building block of proteins, not the end product of lipid digestion.

3. How long can Vitamin A be stored in the liver for at least?

• A. 1 month.
• B. 6 months.
• C. 1 year.
• D. 18 months.

Correct answer: C

Rationale: Vitamin A can be stored in the liver to meet basic needs for at least 1 year. This storage capacity allows the body to have a reserve of Vitamin A to sustain its needs over an extended period. Choices A, B, and D are incorrect because they underestimate the storage capacity of Vitamin A in the liver, which can last longer than these durations.

4. What is a major constituent of cell membranes?

• A. cholesterol
• B. phospholipid
• C. saturated
• D. triglyceride

Correct answer: B

Rationale: Phospholipids are a major component of cell membranes, providing structural integrity and facilitating cell signaling. Cholesterol (choice A) is also present in cell membranes but in smaller amounts and plays a different role. Saturated (choice C) and triglyceride (choice D) are not major constituents of cell membranes.

5. In managing Type 2 diabetes, what is the most important dietary change?

• A. Increase carbohydrate intake
• B. Increase fiber intake
• C. Increase protein intake
• D. Reduce fat intake

Correct answer: B

Rationale: Increasing fiber intake can help regulate blood sugar levels in patients with Type 2 diabetes.
