Question

1. in the chart below, list the functions of each biomolecule.

biomolecule	function in organisms
protein
lipid
nucleic acid

Explanation:

To fill the table, we use knowledge of biomolecules from Biology (a subfield of Natural Science).

• Carbohydrate: Main source of energy (e.g., glucose for cellular respiration), structural support (e.g., cellulose in plant cell walls).
• Protein: Structural (e.g., collagen), enzymatic (catalyze reactions), transport (e.g., hemoglobin), immune (e.g., antibodies), regulatory (e.g., hormones like insulin).
• Lipid: Energy storage (e.g., fat), structural (cell membrane phospholipids), insulation, protection, signaling (e.g., steroid hormones).
• Nucleic Acid: Store and transmit genetic information (DNA: hereditary material; RNA: involved in protein synthesis).

Answer:

Biomolecule	Function in Organisms
Protein	Structural (e.g., collagen), enzymatic (catalyze reactions), transport (e.g., hemoglobin), immune (e.g., antibodies), regulatory (e.g., insulin)
Lipid	Energy storage (e.g., fats), structural (cell membrane), insulation, protection, signaling (e.g., steroid hormones)
Nucleic Acid	Store/transmit genetic info (DNA: hereditary; RNA: protein synthesis)
