Verified step by step guidance

Understand the role of fats in animal bodies: Fats, also known as lipids, are essential macromolecules that serve specific functions such as energy storage and insulation.

Energy storage: Fats are stored in adipose tissue and provide a dense source of energy. They contain long hydrocarbon chains that, when metabolized, release significant amounts of ATP during cellular respiration.

Insulation: Fats help maintain body temperature by providing thermal insulation. The adipose tissue beneath the skin acts as a barrier to prevent heat loss, especially in cold environments.

Eliminate incorrect options: Transporting oxygen and providing structural support to cell walls is incorrect because oxygen transport is primarily carried out by hemoglobin, and cell walls are not present in animal cells (they are found in plants). Catalyzing metabolic reactions and forming nucleic acids is incorrect because enzymes (proteins) catalyze reactions, and nucleic acids are formed from nucleotides, not fats.

Confirm the correct answer: The correct uses of fats in animals are energy storage and insulation, as these are well-established biological functions of lipids in animal physiology.
