AP Biology Chapters 1 – 5 Study Guide Chapter One This is a review chapter so you should know most of this information. Specifically review: Emergent properties Reductionism vs. systems biology approach Difference in prokaryotes and eukaryotes Difference in positive and negative feedback Darwin’s concept of natural selection Experimentation: a good hypothesis, control vs experimental groups,dependent and independent variables, limits of experimentation in science, discovery science vs. hypothesis-based science, graphing Chapters Two and Three You should already know basic chemistry, such as make-up of atoms, what elements, compounds, etc. are. The test will not focus on these elemental concepts but rather on how chemistry affects biology. Specifically review: How to determine reactivity of elements (valence, valence number, electron arrangement) What isotopes are, how differ, how used in biology Difference in intramolecular bonds: ionic, covalent (polar and nonpolar) Types of intermolecular bonds: hydrogen bonds, Van der Waals forces The polarity of the water molecule and how it affects its hydrogen bonding Unique properties of water and how you can explain them using hydrogen bonding: adhesion, cohesion, high specific heat, ice expansion upon freezing, good solvent ability, transpiration, etc. Why this is all important in the living world. The concept of pH, how to determine concentrations of H and OH ions, how these differ in acids and bases, pH scale, acid rain, coral reef degradation Buffers, what they are, carbonic acid/bicarbonate buffering system in our bodies How to make molar solutions Chapters Four and Five A lot of biology (biochemistry) here that you need to know. Specifically think about how structure determines functionality. Specifically review: Why carbon is important in the living world, its bonding capabilities, organic chemistry The three different types of isomers, identify, why isomers are important The functional groups in organic molecules, what properties they bestow Polymers, monomers How monomers are joined in condensation reactions, and separated in hydrolysis Four main types of macromolecules, know: Their monomers (or components in case of lipids) How you can recognize them Their functions Their properties (polar, nonpolar) Types of linkages that link them together For carbohydrates – specifically simple sugars and starches, polysaccharides, storage and structural, plant and animal polysaccharides, chitin For lipids – how assembled, types such as phospholipids, triglycerides, steroids For proteins – levels of structure, bonding in each level, how structure is achieved and importance, how mutations affect structure (SCA) For nucleic acids – basic differences in DNA and RNA
