1. Plant stanols and sterols help to lower LDL cholesterol and are often added to which food product?
- A. margarine
- B. milk
- C. cereal
- D. yogurt
Correct answer: A
Rationale: Plant stanols and sterols are commonly added to margarine to help lower LDL cholesterol levels. Margarine acts as a vehicle for these compounds, making it easier for individuals to incorporate them into their daily diet. While milk, cereal, and yogurt are healthy food options, they are not typically enriched with plant stanols and sterols for cholesterol-lowering purposes, making them less likely candidates as the correct answer.
2. What is the conversion of genetic information in RNA into a sequence of amino acids?
- A. translation
- B. transcription
- C.
- D.
Correct answer: A
Rationale: The correct answer is 'translation.' Translation is the process where the genetic information in messenger RNA (mRNA) is decoded to produce a specific sequence of amino acids, forming a protein. This process occurs at ribosomes within the cell. Option B, 'transcription,' is incorrect as transcription is the process of synthesizing mRNA from a DNA template. Options C and D are irrelevant as they are not related to the conversion of genetic information into amino acids.
3. What dietary factor raises triglyceride levels?
- A. high refined carbohydrate intake
- B. low soluble fiber intake
- C. high iron intake
- D. low fat intake
Correct answer: A
Rationale: The correct answer is A: high refined carbohydrate intake. High intake of refined carbohydrates, such as sugars and white flour, can lead to elevated triglyceride levels, increasing the risk of cardiovascular disease. Choice B, low soluble fiber intake, is incorrect because soluble fiber actually helps lower triglyceride levels. Choice C, high iron intake, is incorrect as iron intake is not directly linked to raising triglyceride levels. Choice D, low fat intake, is also incorrect as not all fats raise triglyceride levels; it depends on the type of fat consumed.
4. Which of the following is a common sign of vitamin D deficiency?
- A. Brittle nails
- B. Muscle weakness
- C. Night blindness
- D. Hair loss
Correct answer: B
Rationale: Muscle weakness is a common sign of vitamin D deficiency. Vitamin D is essential for calcium absorption and bone health, and its deficiency can lead to muscle weakness. Brittle nails (Choice A) are not typically associated with vitamin D deficiency. Night blindness (Choice C) is related to vitamin A deficiency, not vitamin D deficiency. Hair loss (Choice D) can be linked to various factors, but it is not a common sign of vitamin D deficiency.
5. If a person could not make bile, what would happen?
- A. experience fatigue, as the body would not be able to make lipid carriers to deliver fat to body cells for energy
- B. have less cholesterol being made by the liver
- C. need to consume higher levels of fat
- D. be unable to absorb most lipids, and fat would be excreted in the feces
Correct answer: D
Rationale: The correct answer is D. Bile is essential for emulsifying fats in the small intestine, allowing them to be absorbed. Without bile, most fats would not be absorbed and would be excreted in the feces. Choices A, B, and C are incorrect because the primary role of bile is in the digestion and absorption of fats, rather than affecting lipid carriers, cholesterol production, or dietary fat consumption.
