Chapter 6: What is metabolism? What is a catabolic pathway? Give an example. What is an anabolic pathway? Give an example. What is energy? Potential energy? Kinetic energy? Give the 2 laws of Thermodynamics Know the difference between a spontaneous & a nonspontaneous reaction. Does a spontaneous reaction require the input of energy? What happens during a spontaneous change? If my G (change in free energy) is positive, then my products have more free energy than my reactants. True or False If my G (change in free energy) is negative, then my products have less energy than my reactants. True or False What is an exergonic reaction? Is it catabolic or anabolic? What is an endergonic reaction? Is it catabolic or anabolic? What is activation energy? What is a catalyst? How do enzymes affect a chemical reaction? When referring to an enzyme, what is the active site? Know the difference between a competitive & a noncompetitive inhibitor. What is feedback inhibition & why is it important? Chapter 7 Explain the difference between an autotroph & a heterotroph What is meant when we say a substance is oxidized/reduced? Know the formula for cellular respiration & what substances get oxidized & reduced. Briefly name & describe the stages of cellular respiration. What are the products of glycolysis? Where in the cell does this take place? What process producesATP during glycolysis (hint: involves an enzyme & a substrate)? If oxygen is not present after glycolysis, what pathway does it use? Where in the cell does the citric acid cycle (Krebs cycle) occur? What are the products of the citric acid cycle? Oxidative phosphorylation consists of what 2 processes? How manyATP does the ETC generate? What is transferred out into the intermembrane space of the mitochondria during ETC & what does this create? What is the protein that drivesATP synthesis called? What is the final electron acceptor in aerobic oxidative phosphorylation? Chapter 8 Macroscopically, where on the plant are the sites for photosynthesis? Microscopically, where in the plants does photosynthesis occur? Where are chloroplasts found within the leaf? Know the terms thylakoid, grana, & stroma. Is photosynthesis an endergonic or exergonic process? What are the stages in photosynthesis? Which color of light works best for photosynthesis? Where do the light reactions take place? What happens during the light reactions? Know the term: photophosphorylation. How many photosystems are there in the light reactions? Which one functions first? What wavelength is photosystem II best at absorbing? How about photosystem I? What 2 things essentially power the Calvin cycle? Where does the Calvin cycle take place? Know the 3 phases of the Calvin cycle. Chapter 9 Know the 4 types of signaling & some examples of each. Know the 3 types of cell surface receptors. What is a ligand? Why, in signaling molecules, is the property of being lipid-soluble so crucial? *Remember signaling molecules can vary and include: small hydrophobic, water soluble, & gaseous* What are second messengers? Give examples. Chapter 10 What is mitosis? What is the process in which bacteria divide? How many total chromosomes do human cells have?Arranged in how many pairs? What do we mean when we say that humans are diploid? Know the difference between somatic cells, germ cells, & gametes. What are the 2 overall stages of the cell cycle & what happens in each of them? What happens during S phase of interphase? What is G 0hase? What type of cells would be in this phase? Know the stages of Mitosis. What is cytokinesis? What forms when animal cells are undergoing cytokinesis? In plant cells? What are oncogenes? What are proto-oncogenes? Know the terms benign tumor, malignant tumor, & metastasize.
