1. What is the form in which energy from excess intake of proteins, fats, alcohol, and carbohydrates is stored?

• A. Protein
• B. Fat
• C. Carbohydrates
• D. Alcohol

Correct answer: B

Rationale: When the body consumes more energy than it needs, the surplus is stored as fat, regardless of whether the energy source was proteins, fats, alcohol, or carbohydrates. This is why the correct answer is 'Fat'. Other choices are incorrect because, in excess intake situations, the body does not store surplus energy as proteins, carbohydrates, or alcohol.

2. What differentiates one amino acid from another?

• A. The amine group
• B. The acid group
• C. The side chain
• D. None of the above

Correct answer: C

Rationale: The side chain, also known as the R group, is what differentiates one amino acid from another. It imparts unique properties to each amino acid, thereby influencing their roles and functions in proteins. The amine group (Choice A) and the acid group (Choice B) are components of all amino acids and do not cause the differences among various amino acids. Choice D is incorrect as it suggests that none of the given options account for the differences, which is not true as the side chain does.

3. Where in the body are microvilli located, facilitating the absorption of most nutrients?

• A. Stomach
• B. Pancreas
• C. Large Intestine
• D. Small Intestine

Correct answer: D

Rationale: The correct answer is D: Small Intestine. Microvilli are present in the small intestine, significantly increasing its surface area for efficient absorption of nutrients. The small intestine is the primary site for nutrient absorption in the body. The stomach (choice A) primarily functions to break down food with its acidic environment but is not where most nutrients are absorbed. The pancreas (choice B) produces enzymes to aid in digestion but does not directly absorb nutrients. The large intestine (choice C) mainly absorbs water and electrolytes from undigested food, rather than nutrients.

4. Being in contact with reality and the environment is a function of the:

• A. conscience
• B. ego
• C. id
• D. super ego

Correct answer: B

Rationale: Being in contact with reality and the environment is a function of the ego. The ego is responsible for mediating between the id's basic desires, the superego's idealistic standards, and the real world. The conscience (not listed as a choice) is related to feelings of guilt or moral responsibility. The id represents primal instincts, and the superego represents the internalized ideals and moral standards.

5. Match the energy-yielding nutrient to the amount of energy it provides to the body: Carbs, Fats, Proteins.

• A. Carbs - 4kcal/g
• B. Fats - 9kcal/g
• C. Proteins - 4kcal/g
• D. All of the above

Correct answer: D

Rationale: The correct answer is D, All of the above. Carbohydrates and proteins provide 4 kcal per gram, while fats provide 9 kcal per gram. Therefore, all three energy-yielding nutrients provide different amounts of energy to the body. Choice A, B, and C are incorrect because each of them individually provides a specific amount of energy per gram, but when considering all nutrients together, they collectively cover the spectrum of energy provision to the body.
