1. What are the compounds in soy foods with estrogen-like activity examples of?

• A. Indispensable amino acids.
• B. Phytochemicals.
• C. Neurotransmitters.
• D. Metabolic by-products.

Correct answer: B

Rationale: The correct answer is B: Phytochemicals. Phytochemicals in soy foods can mimic estrogen and may have health benefits. Indispensable amino acids are essential amino acids that the body cannot produce on its own. Neurotransmitters are chemical messengers in the nervous system. Metabolic by-products are substances produced during metabolism.

2. Which gastric enzyme present in infants coagulates milk?

• A. Casein.
• B. Pepsinogen.
• C. Trypsin.
• D. Rennin.

Correct answer: D

Rationale: The correct answer is D, rennin. Rennin is the enzyme in infants responsible for coagulating milk, which aids in the digestion process. Choice A, casein, is a milk protein and not an enzyme. Choices B and C, pepsinogen and trypsin, are digestive enzymes but are not specifically involved in coagulating milk in infants.

3. Amino acids that can be synthesized by the body in sufficient amounts are known as:

• A. indispensable.
• B. dispensable.
• C. simple.
• D. complex.

Correct answer: B

Rationale: The correct answer is B, 'dispensable.' Dispensable amino acids are those that the body can synthesize in sufficient amounts, so they are not required to be obtained from the diet. Indispensable amino acids, on the other hand, are essential and must be obtained from the diet because the body cannot produce them in sufficient quantities. Choices C and D, 'simple' and 'complex,' are incorrect as they do not accurately describe amino acids in terms of synthesis by the body.

4. Which age group is particularly vulnerable to malnutrition?

• A. Infants
• B. Teenagers
• C. Young adults
• D. Middle-aged adults

Correct answer: A

Rationale: Infants are particularly vulnerable to malnutrition due to their high growth rate and specific nutrient requirements. During the first year of life, infants experience rapid growth and development, requiring essential nutrients for proper physical and cognitive development. Teenagers, young adults, and middle-aged adults have more stable nutritional needs compared to infants, making them less vulnerable to malnutrition. Therefore, infants are the most susceptible age group when it comes to malnutrition.

5. How are lipids carried in the bloodstream?

• A. Micelles.
• B. Glycolipids.
• C. Lecithin.
• D. Lipoproteins.

Correct answer: D

Rationale: Lipids are carried in the bloodstream in the form of lipoproteins. Lipoproteins are complexes of proteins and lipids that transport fats to various parts of the body. While micelles, glycolipids, and lecithin are all related to lipid metabolism, they are not the primary carriers of lipids in the bloodstream. Micelles are small lipid clusters in the intestines, glycolipids are lipids with a carbohydrate attached, and lecithin is a type of phospholipid. Therefore, lipoproteins are the correct answer as they are specifically designed for transporting lipids through the bloodstream.
