Question

which two are important roles of carbohydrates? select all correct options structural support insulation control chemical reactions as enzymes code for traits energy source

Explanation:

Carbohydrates provide structural support in plants (e.g., cellulose in cell - walls) and are a major energy source for organisms. They are not for insulation (lipids do that), do not control chemical reactions as enzymes (proteins do that), and do not code for traits (nucleic acids do that).

Answer:

• Structural support
• Energy source
