Question

which of the following categories of organic molecules is correctly paired with one of its functions? a proteins: provide quick, short - term energy to cells b lipids: provide slow, long - term energy to cells c nucleic acids: digest dead cells d carbohydrates: store genetic information

Explanation:

• Option A: Proteins primarily function in structure, enzymes, and signaling, not quick energy (carbohydrates do this).
• Option B: Lipids (e.g., fats) store energy long-term and release it slowly, which is correct.
• Option C: Nucleic acids (DNA/RNA) store genetic info, not digest dead cells (lysosomal enzymes do this).
• Option D: Carbohydrates provide energy, not store genetic info (nucleic acids do this).

Answer:

B. lipids: provide slow, long-term energy to cells
