Both are a source of energy. Both are replicated during meiosis. Both lower the activation energy of reactions. Both dissolve nutrients in the digestive system.
I gave my students this multiple choice question: How are the functions of a carbohydrate and a lipid similar?

Only one answer is correct among these 4 choices:
- Both are a source of energy.
- Both are replicated during meiosis.
- Both lower the activation energy of reactions.
- Both dissolve nutrients in the digestive system.

Could you tell me which one is correct?

Both are a source of energy.
