Analyze Question 7

The question asks for the main function of lipids in living things.

• Short-term energy storage is primarily the role of carbohydrates.
• Long-term energy storage and insulation are key functions of lipids (fats).
• Immunity is primarily assisted by proteins (antibodies).
• Genetic information is stored and transmitted by nucleic acids (DNA and RNA).

Therefore, the correct option is the second one.

Analyze Question 8

The question asks which of the options is NOT a function of proteins in living things.

• Driving chemical reactions as a catalyst is a primary function of enzymatic proteins.
• Providing immunity via antibodies is a key function of defensive proteins.
• Structure and transport through the cell membrane are essential roles of structural and transport proteins.
• Providing energy is not a primary function of proteins; carbohydrates and lipids are the main energy sources, while proteins are spared for structural and functional roles.

Therefore, the correct option is the first one.
