All living organisms are composed of four major classes of large biological molecules, often referred to as the "molecules of life": carbohydrates, lipids, proteins, and nucleic acids. These biomolecules serve as the fundamental building blocks essential for the development, maintenance, and replication of life forms. Carbohydrates act as primary fuel sources and structural materials. Proteins exhibit a vast diversity of structures to perform cellular machinery functions and catalyze reactions. Nucleic acids, such as DNA and RNA, are critical for storing and transmitting hereditary genetic information. While lipids are also a major class, carbohydrates, proteins, and nucleic acids represent the primary organic compounds that form the molecular basis of all life. Therefore, all the listed options are essential molecules of life found across all biological systems.
