1. What is the process of converting glycogen to glucose called?

• A. Glucogenesis.
• B. Glycogenolysis.
• C. Glyconeogenesis.
• D. Gluconeogenesis.

Correct answer: B

Rationale: The correct answer is B: Glycogenolysis. Glycogenolysis is the process of breaking down glycogen into glucose. Choices A, C, and D are incorrect. Glucogenesis (choice A) is not a term used in biochemistry. Glyconeogenesis (choice C) refers to the synthesis of new glucose molecules from non-carbohydrate sources, not the breakdown of glycogen. Gluconeogenesis (choice D) is the process of producing glucose from non-carbohydrate sources, not the breakdown of glycogen.

2. What does the Tolerable Upper Intake Level (UL) represent?

• A. a replacement for Recommended Dietary Allowances (RDAs).
• B. a safe level of intake for people of all ages.
• C. a potentially toxic level of intake of a nutrient.
• D. the highest amount of a nutrient that can be safely consumed.

Correct answer: D

Rationale: The Tolerable Upper Intake Level (UL) represents the highest amount of a nutrient that can be safely consumed without causing adverse health effects. It is not a replacement for Recommended Dietary Allowances (RDAs) (choice A) which are nutrient intake recommendations. While the UL is established to prevent toxicity, it is not a completely safe level for people of all ages (choice B). It is also not a potentially toxic level of intake of a nutrient (choice C), but rather the level that is unlikely to cause adverse health effects.

3. A physical science that contributes to understanding how nutrition relates to health and well-being is:

• A. anatomy
• B. biochemistry
• C. physics
• D. pharmacology

Correct answer: B

Rationale: Biochemistry is the correct answer because it focuses on understanding the chemical processes related to nutrition and how nutrients affect the body. Anatomy (choice A) primarily deals with the structure of organisms, not the chemical processes of nutrition. Physics (choice C) deals with energy and matter, not specifically related to nutrition. Pharmacology (choice D) focuses on drugs and their interactions with the body, not directly related to nutrition and its effects on health.

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 rhythmic contractions that propel food through the intestinal tract called?

• A. Segmentation
• B. Peristalsis
• C. Cardiospasm
• D. Pendular movements

Correct answer: B

Rationale: Peristalsis is the correct answer because it refers to the rhythmic contractions that propel food through the intestinal tract by pushing it along the digestive system. Segmentation, on the other hand, refers to the mixing movements in the intestines rather than the forward movement of food. Cardiospasm is a condition characterized by difficulty swallowing due to the inability of the esophagus to relax, and pendular movements are a type of motility found in the small intestine but do not specifically refer to the propulsion of food.
