Question

which of the following is a function of lipids in living organisms? store genetic information; speed up chemical reactions; long - term energy storage; provide structural support to cell walls

Explanation:

• Storing genetic information is a function of nucleic acids (like DNA/RNA), not lipids.
• Speeding up chemical reactions is the role of enzymes (proteins), not lipids.
• Lipids, such as fats and oils, are known for long - term energy storage in organisms. They can store more energy per gram compared to carbohydrates.
• Providing structural support to cell walls is a function of cellulose (a carbohydrate) in plant cell walls, not lipids.

Answer:

Long - term energy storage (the option with the orange background: "Long - term energy storage")
