What dietary factor raises triglyceride levels?

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.

Correct Answer: B

Rationale: The statement is FALSE. The Acceptable Macronutrient Distribution Ranges recommend that 10-35% of daily calories come from protein, not half. The remaining calories should be derived from a combination of carbohydrates and fats to ensure a balanced diet. Choosing option A is incorrect because it misinterprets the recommended percentage for protein intake. Options C and D are left blank as they are not applicable to the question.

Correct Answer: A

Rationale: The correct answer is A: 'breaks down carbs.' Amylase is an enzyme that specifically targets carbohydrates, breaking them down into simpler sugars like maltose. This process aids in the digestion of carbohydrates in the human body. Choices B, C, and D are incorrect because amylase does not break down proteins, lipids, or directly aid fat digestion. Proteins are broken down by proteases, lipids are broken down by lipases, and fat digestion is primarily assisted by bile salts and lipases in the small intestine.

Correct Answer: A

Rationale: The correct answer is A, fatty acid. During the process of lipid digestion, triglycerides are broken down into fatty acids and glycerol. These end products are then absorbed into the bloodstream or lymphatic system for further processing. Choices B, C, and D are incorrect because sucrose is a disaccharide, monosaccharide is a simple sugar unit, and amino acid is a building block of proteins, not the end product of lipid digestion.

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.
