Question

4 multiple choice 20 points what type of biomolecule is an enzyme? lipid carbohydrate protein

Explanation:

Enzymes are biological catalysts, and most enzymes are proteins (some are RNA, but in typical basic biology contexts, the primary answer is protein). Lipids are for energy storage, structure, etc., and carbohydrates are for energy and structure, not enzyme function. So the correct option is protein.

Answer:

C. protein (assuming the options are labeled as A. lipid, B. carbohydrate, C. protein; if labels differ, adjust to match the correct option text with its identifier)
