1. Which of the following foods are major sources of starch?

• A. Fruits
• B. Meats
• C. Legumes
• D. Milk

Correct answer: C

Rationale: The correct answer is C: Legumes. Legumes, such as beans and lentils, are major sources of starch, providing complex carbohydrates. Fruits (choice A) mainly provide sugars rather than starch. Meats (choice B) and milk (choice D) are not significant sources of starch as they mainly provide protein and fats, respectively. Therefore, choices A, B, and D are incorrect.

2. Most fat replacers are made from:

• A. proteins.
• B. carbohydrates.
• C. cholesterol.
• D. monoglycerides.

Correct answer: B

Rationale: Most fat replacers are made from carbohydrates. Carbohydrates are utilized to mimic the texture of fats in food products. Proteins (Choice A) are not commonly used as fat replacers and are more often associated with other functions in food. Cholesterol (Choice C) is a type of fat and not used to replace fat in food products. Monoglycerides (Choice D) are sometimes used as emulsifiers or stabilizers in food products but are not the primary source of fat replacers.

3. 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.

4. The release of gastric secretions is stimulated by nerve and hormonal stimuli and the:

• A. ingestion of water.
• B. swallowing reflex.
• C. presence of food in the stomach.
• D. closing of the pyloric sphincter.

Correct answer: C

Rationale: The correct answer is C: 'presence of food in the stomach.' Gastric secretions are stimulated when food enters the stomach, triggering nerve and hormonal responses. This process prepares the stomach for digestion. Choices A, B, and D are incorrect because ingesting water, swallowing reflex, and the closing of the pyloric sphincter do not directly stimulate the release of gastric secretions.

5. What is the term for the production of glucose from protein, lactate, or glycerol?

• A. glycolysis
• B. gluconeogenesis
• C. glycogenolysis
• D. glucogenesis

Correct answer: B

Rationale: Gluconeogenesis is the correct term for the production of glucose from non-carbohydrate sources such as protein, lactate, or glycerol. Choice A, glycolysis, is the process of breaking down glucose into pyruvate. Choice C, glycogenolysis, is the breakdown of glycogen into glucose. Choice D, glucogenesis, is not a recognized term in biochemistry.
