d. 25

1. 9. which nutrient does not supply the body with energy? (1 point) *

a. vitamins
b. fats
c. carbohydrates
d. proteins

Explanation:

• Question 11.7: Saturated fats have a high melting point due to their straight - chain structure (no double bonds to disrupt packing), so they are usually solid at room temperature. Polyunsaturated and monounsaturated fats have double bonds (cis - double bonds in natural forms) that cause kinks in the chain, making them liquid at room temperature. Cholesterol is a lipid but not a fat in the triglyceride sense relevant to this question.
• Question 12.8: Dietary guidelines recommend that simple carbohydrates (added sugars) should be no more than 10% of daily calories. Excessive simple carbohydrate intake (especially added sugars) is linked to health issues like obesity and diabetes.
• Question 13.9: Vitamins are essential for various metabolic processes (such as acting as co - factors in enzyme - catalyzed reactions), but they do not provide energy. Fats, carbohydrates, and proteins are macronutrients that can be metabolized to release energy (fats: 9 kcal/g, carbohydrates: 4 kcal/g, proteins: 4 kcal/g).

Answer:

11.7: A. saturated fats
12.8: B. 10
13.9: A. vitamins
