Building Blocks of Life Macromolecules and Their Functions

Mrs. G introduces macromolecules, essential for life, including carbohydrates, lipids, proteins, and nucleic acids. She explains monomers and polymers, detailing how macromolecules are formed. Carbohydrates provide energy, lipids store energy, proteins build tissues, and nucleic acids store genetic information. The video also covers the elements in macromolecules.
