Answer

Brief Explanations:

Proteins are macromolecules made of carbon, hydrogen, oxygen, and nitrogen and can catalyze cellular reactions. Nucleic acids are mainly for storing and transmitting genetic information. Lipids are mainly for energy - storage and membrane - formation and do not have nitrogen as a main component in the same way as proteins. Carbohydrates are composed of carbon, hydrogen, and oxygen and are mainly for energy - supply.

Answer:

D. proteins
