Part II: Proteins & Nucleic Acids. The FOUR Classes of Large Biomolecules. All living things are made up of four classes of large biological molecules: . Carbohydrates . Lipids. Protein. N. ucleic Acids. Introducing proteins. Proteins. are a diverse group of large and complex polymer molecules, made up of long chains of . amino acids. .. They have a wide range of biological roles, including:. structural:. B3. Matter. Made from the building blocks known as atoms. Atoms: contain subatomic particles . protons, neutrons, electrons. Ground state: electrons at the lowest energy level. Excited state: electrons at highest energy level. Carbon-based molecules are the foundation of life.. Bonding Properties of Carbon. Carbon forms covalent bonds with up to four. . other atoms, including other carbon atoms.. 1. 2. 3, 4. Structure of carbon-based molecules…. Structures, Functions and Organelle Relationships. p.50-50 in textbook. Animal Cell. Plant Cell. Cell Membrane & Cell wall. The cell membrane (plasma membrane) creates a cell boundary and helps to regulate the transport of molecules in and out of the cell (in plant & animal cells). Cell Structure and Function Chapter 2 Lesson 1: Cells and Life Understanding Cells People didn’t always know about cells Too small to be seen without proper tools Robert Hooke (English Scientist) 300 years ago he built a microscope The Structure and Function of Macromolecules Part II: Proteins & Nucleic Acids The FOUR Classes of Large Biomolecules All living things are made up of four classes of large biological molecules: Carbohydrates and Lipids . (Ch. 5-1 and Ch. 5-2). Describe the properties of the monomers and the type of bonds that connect the monomers in biological macromolecules.. Explain how hydrolysis and dehydration synthesis are used to cleave and form covalent bonds between monomers.. Overview: The Molecules of Life. Within cells, small organic molecules are joined together to form larger molecules. Macromolecules are large molecules composed of thousands of covalently connected atoms.
