Question

which organic molecule is paired with its function?
nucleic acid : to store energy
lipids : to regulate metabolic processes
carbohydrate : to provide quick - release energy
proteins : to provide insulation

Explanation:

• For "nucleic acid : to store energy", nucleic acids (like DNA and RNA) are mainly for storing and transmitting genetic information, not energy storage.
• For "lipids : to regulate metabolic processes", lipids are mainly for energy storage, insulation, and forming cell membranes. Regulatory functions are more associated with proteins (like enzymes and hormones) or nucleic acids in some cases.
• For "carbohydrate : to provide quick - release energy", carbohydrates (such as glucose) are broken down quickly in the body to release energy, which is correct.
• For "proteins : to provide insulation", proteins have functions like structural support, enzyme catalysis, transport, etc. Insulation is a function of lipids (like fat).

Answer:

C. carbohydrate : to provide quick - release energy
