Review: Chapter 5, 6, 7, and 8 Chapter 5: Membranes o What is a lipid bilayer? What does it consist of? o Extracellular fluid vs. intracellular fluid o Membrane structure o Integral proteins (transmembrane proteins) function o Peripheral proteins o The purpose of cholesterol in animal cells o 3 functions of membrane proteins o Alpha helix vs. single alpha helix vs. beta barrels vs. multiple alpha helices and beta barrels o Passive Transport vs. Active Transport Simple Diffusion vs. facilitated diffusion vs. osmosis What are aquaporins? Cotransport vs. coutnertransport Endocytosis vs. exocytosis o Concentrations (isotonic vs. hypotonic vs. hypertonic) What do plant cells like to be? What do animal cells like to be? Chapter 6: Energy and Metabolism o Where does all our energy come from? o What is ATP? o Cation vs. anion o REDOX reactions o Endergonic vs. Exergonic In each reaction which has more energy products or reactants? o Enzymes Activation energy Functions of enzymes Define a substrate and active site What is a ribozyme? Factors that control enzymes Inhibitors Competitive vs. Noncompetitive Activator enzymes o Metabolism Anabolic vs. Catabolic reactions o Positive vs. Negative Feedback Give an example of each o ATP hydrolysis Chapter 7: How Cells Harvest Energy o Cellular respiration Products and reactants What is oxidized? Reduced? What has more energy reactants or products? o The steps of cellular respiration Glycolysis Where does it take place? Enzymes that work with it Products Pyruvate Oxidation Where does it take place? Enzyme that work with it Products Krebs Cycle/Citric Acid Cycle Where does it take place? How many times does this occur? Products Electron Transport Chain (ETC) Where does it take place? How does it work? Name all 3 types of hydrogen pumps What are the products Chemiosmosis Where does it take place? What is the last electron carrier of cellular respiration? o ATP Synthase How does it work? Where is it? Proton gradient? Down or up the concentration gradient? o Absence of oxygen (Fermentation) Lactic acid fermentation vs. Ethanol Fermentation Where does it occur? What are the products? What are the last electron carriers? What are some of the last electron acceptors for bacteria? Define a methanogens o Overall (theoretical) yield of ATP How much ATP does NADH and FADH produce? 2 How much ATP does glycolysis? Pyruvate oxidation? Krebs Cycle? ETC? produce What is the ACTUAL yield of ATP o How to control aerobic respiration? Is this positive or negative feedback? o The importance of eating proteins, fats, and carbs? Chapter 8: Photosynthesis o What are the products? Reactants? o What is oxidized? Reduced? o Catabolic? Anabolic? Exergonic? Endergonic? o How is this related to cellular respiration? o The leaf structure What is mesophyll? Chloroplast? Thylakoids? Grana? Leaf veins? Bundle sheath cells? Examples of it? Stoma vs. Stroma o Lightdependent reactions vs. lightindependent reactions o What are pigments? Chlorophyll a vs. chlorophyll b vs. carotenoids What are accessory pigments? Why do plants change colors in the fall? o Photosystems PSI vs. PSII Which one comes first? What are the main differences? o Electrons in the reaction center What is reduced and what is oxidized o What keeps plants from dry weather? Photorespiration? C4 vs C3 plants vs. CAM plants
