The Building Blocks of Life: Understanding Molecules and Biomolecules

TLDRAll living organisms are made up of atoms that can bond to form molecules. Earth has specific molecules that make it habitable for life, such as water and carbon-based organic molecules. Organisms rely on four main categories of biological molecules: carbohydrates, lipids, proteins, and nucleic acids. These molecules serve as an energy source, structural support, and carry out essential functions in living organisms.
