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. Which of the following is one of the simplest amino acids?

• A. Arginine
• B. Valine
• C. Lysine
• D. Glycine

Correct answer: D

Rationale: The correct answer is Glycine. Glycine is indeed one of the simplest amino acids as it consists of just a hydrogen atom as its side chain. Arginine, Valine, and Lysine are all more complex amino acids compared to Glycine, making them incorrect choices for this question.

3. What is the factor most likely to stimulate digestive secretions?

• A. Smelling or seeing food
• B. Grocery shopping
• C. Fasting
• D. Exercise

Correct answer: A

Rationale: The correct answer is A: Smelling or seeing food. When an individual smells or sees food, it can trigger the body to start producing digestive secretions in anticipation of food consumption. This physiological response helps prepare the digestive system for the incoming meal. Choices B, C, and D are incorrect because grocery shopping, fasting, and exercise do not directly stimulate digestive secretions in the same way that the sight or smell of food does.

4. Which lipoprotein increases the risk of cardiovascular disease?

• A. Low-density lipoprotein (LDL)
• B. High-density lipoprotein (HDL)
• C. Very low-density lipoprotein (VLDL)
• D. Chylomicrons

Correct answer: A

Rationale: The correct answer is A: Low-density lipoprotein (LDL). LDL is often referred to as 'bad cholesterol' because it can lead to plaque buildup in arteries, increasing the risk of cardiovascular disease. High-density lipoprotein (HDL) is considered 'good cholesterol' as it helps remove LDL from the arteries, reducing the risk of cardiovascular issues. Very low-density lipoprotein (VLDL) and chylomicrons are also lipoproteins that transport fats in the bloodstream, but they are not as strongly associated with an increased risk of cardiovascular disease as LDL.

5. The body of scientific knowledge related to nutritional requirements for human growth, maintenance, activity, and reproduction is known as:

• A. physiology.
• B. nutrition science.
• C. biochemistry.
• D. dietetics.

Correct answer: B

Rationale: The correct answer is B: nutrition science. Nutrition science specifically focuses on studying the requirements and functions of nutrients in relation to human growth, maintenance, activity, and reproduction. Choice A, physiology, deals more with the functions of living organisms and their parts, not specifically related to nutrients. Choice C, biochemistry, focuses on the chemical processes and substances that occur within living organisms, not specifically centered on nutritional requirements. Choice D, dietetics, involves the application of nutritional knowledge in planning and managing diets for individuals, but it is more focused on the practical aspect rather than the broader scientific study of nutritional requirements.
