Question

class period: ______

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 recall the functions of each biomolecule:

• 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), signaling (e.g., hormones like insulin).
• Lipid: Energy storage (e.g., fats), structural (cell membrane phospholipids), insulation, protection (e.g., waxes).
• Nucleic Acid (DNA/RNA): Store and transmit genetic information (DNA), protein synthesis (RNA).

Answer:

Biomolecule	Function in Organisms
Protein	Structural (e.g., collagen), enzymatic (catalyze reactions), transport, immune, signaling
Lipid	Energy storage; cell membrane structure; insulation, protection
Nucleic Acid	Store/transmit genetic info (DNA); protein synthesis (RNA)
