Which of the following macromolecules are correctly matched with one of their functions?
nucleic acids—insulate; carbohydrates—catalyze chemical reactions
nucleic acids—catalyze chemical reactions; carbohydrates—insulate
fats—insulate; proteins—catalyze chemical reactions
fats—catalyze chemical reactions; proteins—insulate

The correct option is this: FATS INSULATE; PROTEINS CATALYZE CHEMICAL REACTIONS

Explanation:

The macro molecules that are peculiar to living organisms are carbohydrate, proteins and fat and oil. Each of these macro molecules has its specific functions, which it carries out. For instance, fat is responsible for insulating the body and keeping the body warm. This helps the body to maintain its optimum temperature of 37 degree Celsius.

Proteins are another type of macro molecules. Proteins perform diverse functions in the living organisms, one of these is catalysis of biochemical reaction. Proteins act as catalysts for biochemical reaction by speeding up the rate at which biochemical reaction occur.
