Summary of AP Biology Chemistry Unit
Summary of AP Bio Study Book: Barron?s AP Bio Chemistry Section The biochemistry section includes the following subjects: Atomic Structure, Bonding, Polar and Nonpolar Molecules, Hydrophobic and Hydrophilic Substances, the Properties of Water, Isomers, Organic Compounds, Energy, Enzymes, and Metabolism. Atomic Structure All atoms consist of three subatomic particles: neutrons, protons, and electrons. An atom in the elemental state always has a neutral charge because the number of protons equals the electrons. Isotopes are atoms that have the same atomic number but have a different mass because they have more or less protons than usual.
