1. Which types of acids form the basic building blocks of protein?

• A. fatty
• B. amino
• C. nucleic
• D. omega fatty

Correct answer: B

Rationale: The correct answer is 'B: amino.' Amino acids are the fundamental units that make up proteins. They are essential for various bodily functions, including building and repairing tissues. Choice A, 'fatty acids,' are not the basic building blocks of proteins but rather a type of lipid. Choice C, 'nucleic acids,' are the building blocks of nucleic acids like DNA and RNA, not proteins. Choice D, 'omega fatty acids,' are a specific type of fatty acid known for their health benefits but are not directly related to the building blocks of proteins.

2. The nutrients involved in metabolic regulation and control include minerals, vitamins, and:

• A. amino acids.
• B. carbohydrates.
• C. fats.
• D. water.

Correct answer: D

Rationale: The correct answer is D, water. Water plays a crucial role in metabolic regulation along with vitamins and minerals. While amino acids, carbohydrates, and fats are essential nutrients for various bodily functions, they are not primarily involved in metabolic regulation and control.

3. Consuming 30 g of which nutrient would provide the highest number of kcalories?

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

Correct answer: B

Rationale: The correct answer is B, 'Fat.' Fat provides 9 kcalories per gram, which is more than carbohydrates and proteins that provide 4 kcalories per gram each. Therefore, consuming 30 g of fat would yield a higher number of kcalories compared to the same amount of carbohydrates or proteins. Micronutrients do not significantly contribute to kcalories, making them an incorrect choice in this scenario.

4. Which pathogenic bacterium is associated with peptic ulcer disease and gastric cancer?

• A. Lactobacillus.
• B. Bifidobacterium.
• C. H. pylori.
• D. E. coli.

Correct answer: C

Rationale: The correct answer is H. pylori. This bacterium is known to be associated with the development of peptic ulcers and an increased risk of gastric cancer. Lactobacillus (Choice A) and Bifidobacterium (Choice B) are probiotic bacteria that are beneficial to human health and not associated with causing these conditions. E. coli (Choice D) is a diverse group of bacteria, some of which can be pathogenic, but they are not primarily linked to peptic ulcers and gastric cancer like H. pylori.

5. What is the primary function of protein in the body?

• A. Provide energy.
• B. Regulate metabolic processes.
• C. Control muscle contractions.
• D. Build tissue.

Correct answer: D

Rationale: The primary function of protein in the body is to build and repair tissues. Proteins are crucial for growth, maintenance, and repair of body tissues, including muscles, organs, and skin. While proteins can be a source of energy, their primary role is not to supply energy. Regulating metabolic processes and controlling muscle contractions are functions typically attributed to other nutrients and compounds in the body, such as vitamins and minerals.
