Question

which of the biomolecules store long-term energy?
○ carbohydrates
○ lipids
○ proteins
○ nucleic acids

Explanation:

• Carbohydrates are mainly for short - term energy.
• Lipids are known to store long - term energy (e.g., fats in the body are used for long - term energy storage).
• Proteins are mainly for structural and functional purposes (like enzymes, muscle structure), not long - term energy storage.
• Nucleic Acids (DNA, RNA) are for genetic information storage, not energy storage.

Answer:

B. Lipids
