1. Which of the following is an example of a plasma protein?

• A. Collagen.
• B. Myosin.
• C. Albumin.
• D. Phospholipid.

Correct answer: C

Rationale: The correct answer is C, albumin. Albumin is a plasma protein that plays a crucial role in maintaining fluid balance in the blood. Collagen (choice A) is a structural protein found in connective tissues, not a plasma protein. Myosin (choice B) is a protein involved in muscle contraction, not found in the blood plasma. Phospholipid (choice D) is a type of lipid molecule, not a protein present in plasma.

2. Individuals with optimal nutritional status differ from those with marginal nutritional status in their:

• A. nutrient reserves.
• B. clinical signs.
• C. body weight.
• D. risk of mental illness.

Correct answer: A

Rationale: Individuals with optimal nutritional status differ from those with marginal nutritional status in their nutrient reserves. Optimal nutritional status implies having adequate nutrient reserves, which is lacking in marginal status. Clinical signs (choice B) may or may not be present in both groups and are not the differentiating factor between optimal and marginal statuses. Body weight (choice C) can vary for reasons other than nutritional status. The risk of mental illness (choice D) is not directly related to the comparison between optimal and marginal nutritional status.

3. 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.

4. 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.

5. What is the main body storage form of carbohydrates?

• A. Glycogen.
• B. Starch.
• C. Fat.
• D. Glucose.

Correct answer: A

Rationale: The correct answer is A: Glycogen. Glycogen is the stored form of carbohydrates in the body, primarily found in the liver and muscles. Starch (choice B) is a carbohydrate storage molecule in plants, not in the human body. Fat (choice C) is a different macronutrient and not the main storage form of carbohydrates. Glucose (choice D) is a simple sugar that serves as an energy source, not the main storage form of carbohydrates.
