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

• A. Milk
• B. Soy
• C. Sesame seeds
• D. Sweet potato

Correct answer: A

Rationale: The correct answer is A, Milk. Milk is considered a complete protein as it contains all the essential amino acids required by the body. Soy (choice B) is also a complete protein, containing all essential amino acids. Sesame seeds (choice C) and sweet potato (choice D) are not complete proteins as they lack one or more essential amino acids needed by the body.

2. Nutrients interact in the body to regulate metabolic processes, build and repair tissue, and to:

• A. provide energy.
• B. control cellular wastes.
• C. control hormone levels.
• D. regulate absorption.

Correct answer: A

Rationale: The correct answer is A: provide energy. Nutrients play a crucial role in providing energy for the body's various functions. While they do help in regulating metabolic processes and in building and repairing tissue, the primary function related to energy production. Choices B, C, and D are incorrect as nutrients are not primarily responsible for controlling cellular wastes, hormone levels, or absorption.

3. What is the recommended dietary intake of protein for adults?

• A. 0.5 g/kg.
• B. 0.8 g/kg.
• C. 1.0 g/kg.
• D. 1.5 g/kg.

Correct answer: B

Rationale: The recommended dietary intake of protein for adults is 0.8 grams per kilogram of body weight. This amount is considered adequate for most healthy adults. Choices A, C, and D are incorrect as they do not align with the generally recommended protein intake for adults.

4. What is one function of essential fatty acids?

• A. improve skin integrity.
• B. control lipid digestion.
• C. reduce blood clotting time.
• D. form chylomicrons.

Correct answer: A

Rationale: Essential fatty acids play a crucial role in improving skin integrity by supporting the structure and function of cell membranes. This helps in maintaining healthy skin and promoting overall well-being. The other choices are incorrect because essential fatty acids do not directly control lipid digestion, reduce blood clotting time, or form chylomicrons.

5. Which component of protein contains nitrogen?

• A. Amino group
• B. Carboxyl group
• C. Peptide bond
• D. Side chain

Correct answer: A

Rationale: The correct answer is the amino group. Amino groups are functional groups found in amino acids, which are the building blocks of proteins. These groups contain nitrogen and are essential for the structure and function of proteins. The carboxyl group (choice B) contains carbon, oxygen, and hydrogen, while the peptide bond (choice C) is a covalent bond formed between amino acids in a protein chain. The side chain (choice D) refers to the unique chemical structure attached to the central carbon of an amino acid and varies among different amino acids, but it does not specifically contain nitrogen.
