Question

what is the best conclusion based on this data?
blood is a primary location for energy storage.
fat molecules contain more energy - containing bonds than simple sugars.
a gram of glycogen has twice as much energy as a gram of fat.
the human body stores approximately 1,000 kcal of glucose.

Explanation:

• Analyze each option:
• Option 1: Blood is not a primary location for energy storage.
• Option 2: Fat molecules (lipids) have \(9\) kcal per gram, while simple sugars (like glucose in blood) have \(4\) kcal per gram. So fat molecules contain more energy - containing bonds than simple sugars.
• Option 3: A gram of glycogen has \(4\) kcal per gram and a gram of fat has \(9\) kcal per gram. So a gram of fat has more than twice as much energy as a gram of glycogen.
• Option 4: The human body stores approximately \(100000\) kcal in lipids (fat), not \(1000\) kcal of glucose (glucose in blood is only \(40\) kcal).

Answer:

Fat molecules contain more energy - containing bonds than simple sugars.
