Question

which statement best compares and contrasts lipids and carbohydrates? both are used for energy storage, but only carbohydrates are used for long - term energy storage. both are used for energy storage, but only carbohydrates are used for short - term energy storage. both are used for tissues, but only carbohydrates are used for tissue growth. both are used for tissues, but only lipids are used for tissue growth.

Explanation:

Lipids and carbohydrates are both energy-storage molecules. Carbohydrates (e.g., glucose, glycogen) are for short-term energy, while lipids (e.g., fats) are for long-term storage. The third and fourth options are incorrect because neither is primarily used for tissue growth (proteins fulfill that role). The first option reverses the storage duration.

Answer:

Both are used for energy storage, but only carbohydrates are used for short-term energy storage.
