Question

quick energy
energy; storage
structure
escribir la respuesta

Explanation:

To solve this, we analyze the functions (quick energy, energy storage, structure) and match to biomolecules:

• Quick energy: Glucose (from carbohydrates) gives rapid energy.
• Energy; storage: Starch (plants) or glycogen (animals) store energy long - term.
• Structure: Cellulose (plant cell walls) or chitin (fungal cell walls/exoskeletons) provide structure.

These are roles of carbohydrates (e.g., monosaccharides for quick energy, polysaccharides for storage/structure).

Answer:

Carbohydrates (with examples: Glucose for quick energy, Starch/Glycogen for storage, Cellulose/Chitin for structure)
