Question

A gram of butter provides more energy that a gram of sugar because

• A. Butter is an animal product
• B. Butter has more carbon-hydrogen bonds
• C. Butter is more completely absorbed
• D. Butter contains more ATP

Answer 1

The correct option is B Butter has more carbon-hydrogen bonds

Carbohydrates which includes sugars and starches, contain 4 calories per gram, and are considered one of the main sources of energy for the human body. Fats on the other hand give 9 calories per gram,which is approximately 2.5 times more energy than carbohydrates. Moreover, fats contain more carbon-carbon and carbon-hydrogen bonds than carbohydrates or proteins and are therefore richer in energy.

Therefore, the correct answer is option B.
