Correct Answer is D
Explanation
A. Unsaturated fats (HDL): High-density lipoprotein (HDL) is considered "good cholesterol" because it helps remove LDL cholesterol from the blood, reducing the risk of heart disease.
B. Omega-3 fatty acids: Omega-3 fatty acids are healthy fats that reduce inflammation and lower the risk of heart disease by improving heart health.
C. Omega-6 fatty acids: While excessive omega-6 intake may contribute to inflammation, they are not the primary contributors to plaque buildup in blood vessels like saturated fats (LDL).
D. Saturated fats (LDL): Saturated fats increase low-density lipoprotein (LDL), also known as "bad cholesterol," which contributes to plaque buildup in arteries and increases the risk of heart disease.
Correct Answer is C
Explanation
A. Lipids: Some hormones (e.g., steroid hormones like estrogen and testosterone) are lipid-based, but not all. Hemoglobin is a protein, not a lipid.
B. Glucose: Glucose is a carbohydrate used for energy, not for building hormones or hemoglobin.
C. Proteins: Hormones (such as insulin and growth hormone) and hemoglobin (which carries oxygen in red blood cells) are protein-based molecules essential for bodily functions.
D. Carbohydrates: Carbohydrates provide energy but do not contribute to the structure of proteins like hormones and hemoglobin.
