Answer:
The four groups of macromolecules - carbohydrates, lipids, proteins, and nucleic acids - are appropriately referred to as biological molecules or organic molecules because they are essential building blocks of all living organisms and are composed primarily of carbon and other elements found in living organisms.
Organic molecules are molecules that contain carbon atoms, often combined with hydrogen, oxygen, nitrogen, sulfur, and/or phosphorus. Carbon has unique properties that make it well-suited to serve as the backbone of large, complex molecules, and the ability of carbon to form covalent bonds with many other elements allows for the diversity of organic molecules found in living organisms.
Biological molecules are molecules that are essential for life, and they include the macromolecules that make up cells and tissues in all living organisms. These macromolecules play vital roles in many cellular processes, including energy storage and release, cell structure and support, enzymatic catalysis, and genetic information storage and expression.
Therefore, referring to the four groups of macromolecules as biological molecules or organic molecules is appropriate because they are fundamental components of living organisms and are composed primarily of carbon and other elements commonly found in living organisms.
