1. Which component of fat can be used to make glucose through gluconeogenesis?

• A. Glycogen
• B. Fatty acids
• C. Glycerol
• D. Monoglyceride

Correct answer: C

Rationale: The correct answer is 'Glycerol.' Glycerol, a component of fat, can be converted into glucose through gluconeogenesis. Glycogen (Choice A) is a polysaccharide stored in animals, not a component of fat. Fatty acids (Choice B) are used primarily for energy production through beta-oxidation, not for gluconeogenesis. Monoglyceride (Choice D) is a molecule formed during fat digestion, but it is not the component of fat that can be used to make glucose.

2. How is the enzyme trypsin activated?

• A. By zymogen.
• B. By bile.
• C. By gastrin.
• D. By enterokinase.

Correct answer: D

Rationale: The correct answer is D: By enterokinase. Trypsin is activated by enterokinase, an enzyme secreted by the small intestine. Enterokinase plays a crucial role in converting trypsinogen into its active form, trypsin. Choices A, B, and C are incorrect because trypsin is specifically activated by enterokinase, not by zymogen, bile, or gastrin.

3. 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.

4. The primary responsibility for nutrition care of people in the community belongs to the:

• A. community physician.
• B. public health nurse.
• C. public health nutritionist.
• D. registered dietitian.

Correct answer: C

Rationale: Public health nutritionists work within communities to ensure that populations have access to nutritional resources. They focus on promoting good nutrition, developing programs, and educating the public about healthy eating habits. While community physicians, public health nurses, and registered dietitians may also play roles in promoting nutrition in the community, the primary responsibility for nutrition care typically falls under the purview of public health nutritionists.

5. 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.
