Question

what is the primary function of lipids?
a. to carry genetic information
b. to fight against infections
c. to provide longterm energy storage
d. to speed up chemical reactions

Explanation:

• Option A: Carrying genetic information is the function of nucleic acids (like DNA/RNA), not lipids.
• Option B: Fighting against infections is a function of proteins (like antibodies) or immune cells, not lipids.
• Option C: Lipids, such as fats and oils, are known to provide long - term energy storage in organisms. They can store more energy per gram compared to carbohydrates and are used when the body needs a sustained energy source.
• Option D: Speeding up chemical reactions is the function of enzymes (which are proteins), not lipids.

Answer:

C. to provide longterm energy storage
