Transcript of "Unit 2 at a glance - new curriculum"

  1. 1. Unit at a Glance Unit 2. The Chemistry of Life (12 days) Textbook Readings • Chapters1, 2, 3, 4, 5, 6 or 8 Essential Knowledge 1.d.1 There are several hypotheses about the natural origin of life on Earth, each with supporting scientific evidence. 2.a.1 All living systems require constant input of free energy. 2.a.3 Organisms must exchange matter with the environment to grow, reproduce, and maintain organization. 4.A.1: The subcomponents of biological molecules and their sequence determine the properties of that molecule. 4.B.1: Interactions between molecules affect their structure and function. 4.C.1: Variation in molecular units provides cells with a wider range of functions. Laboratory Exercises • Macromolecules: Building Macromolecules • Enzymes: Effect of Temperature, pH, Enzyme Concentration, and Substrate Concentration on Enzyme Activity [C8] [C4]from Helms o Goal: To determine the effect of temperature, pH, enyzyme concentration, and substrate concentration on the activity of catecholase (wet lab) Equations and Formulas • Gibbs Free Energy Test Traditional test using a free response essay question and numerous multiple choice questions. Topics addressed in Past AP Exams Chapter 1 Exploring Life Controlled experiments
  2. 2. Chapter 2 The Chemical Context of Life Bonding Types Electronegativity Hydrogen bonding Van der Waals Chapter 3: Water and Fitness of the Environment Properties of water as they relate to biological events pH Buffers Chapter 4: Carbon and the Molecular Diversity of Life Carbon bonding Isomers Functional groups Chapter 5: Structure and Function of Macromolecules Monomers vs. polymers Dehydration synthesis vs. hydrolysis Carbohydrate structure Polysaccharides Structural polymers Lipids Phospholipids Steroids Proteins Level of Proteins structure Protein conformation Denaturation Nucleic acids Chapter 6/8: Metabolism Anabolic vs. catabolic reactions Free energy Endergonic vs. exergonic reactions ATP Enzymes Regulation of enzymes Allosteric enzymes
