1. 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.
2. 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.
3. Which cells in the islet of the pancreas are responsible for synthesizing insulin?
- A. Alpha cells
- B. Beta cells
- C. Gamma cells
- D. Delta cells
Correct answer: B
Rationale: Beta cells in the islets of Langerhans in the pancreas are responsible for the production and secretion of insulin, which is crucial for regulating blood glucose levels. Alpha cells, on the other hand, produce glucagon, a hormone that raises blood glucose levels. Gamma cells and Delta cells do not exist in the islets of Langerhans; therefore, they are incorrect choices.
4. One of the most common factors that compromise the vitamin D status of older adults, particularly those living in assisted living communities is _____.
- A. decreased intake of fruits and vegetables
- B. lack of physical activity
- C. malabsorption due to atrophic gastritis
- D. lack of exposure to sunlight
Correct answer: D
Rationale: The correct answer is 'D: lack of exposure to sunlight.' Older adults, especially those in assisted living communities, are at risk of vitamin D deficiency due to spending most of their time indoors, which reduces their exposure to sunlight. Sunlight is essential for the body to produce vitamin D. Choices A, B, and C are less likely to be major factors in compromising vitamin D status. While a decreased intake of fruits and vegetables and lack of physical activity can impact overall health, they are not as directly related to vitamin D status. Malabsorption due to atrophic gastritis may affect the absorption of certain nutrients, but vitamin D synthesis primarily depends on sunlight exposure.
5. What term is used to refer to the beliefs, ideals, and values that direct an organization and give it a sense of purpose?
- A. Philosophy
- B. Mission
- C. Vision
- D. Goals and Objectives
Correct answer: C
Rationale: The correct term for the beliefs, ideals, and values that direct an organization and provide it with a sense of purpose is 'Vision'. A Vision statement outlines the organization's aspirations and goals for the future. Choices A, B, and D are incorrect in this context. 'Philosophy' refers to a system of beliefs or principles, 'Mission' relates to the organization's purpose and primary objectives, and 'Goals and Objectives' are the specific targets set to accomplish the Vision.
