Question

multiple choice question
why is fat superior to carbohydrates for energy storage?

fat is hydrophilic and contains a lot of water.
fat contains more energy per gram.
fat has a higher glycemic index.
fat contains sugars used for energy by cells.

Explanation:

• Option 1: Fat is hydrophobic, not hydrophilic, so this is incorrect.
• Option 2: Fat contains more energy per gram (about 9 kcal/g) compared to carbohydrates (about 4 kcal/g), making it superior for energy storage.
• Option 3: Glycemic index relates to carbohydrate digestion, not fat, so this is wrong.
• Option 4: Fat does not contain sugars; sugars are in carbohydrates, so this is incorrect.

Answer:

B. Fat contains more energy per gram.
