Microbiology Bio Study Guide Exam 2 (5,6,7, 20) Chapter 5: Microbial Metabolism Be able to define and explain the following terms: Metabolism Catalysis Photosynthesis/respiration Oxidation/reduction Activation energy, substrate, catalyst What factors influence the rate of reaction for an enzyme? What are the ways that ATP is produced. Know the different parts of an enzyme and how they function Know how the following reactions work Oxidation-reduction Dehydration Respiration Know where the steps occur What types of reactions occur and where they happen. The major enzymes involved. Know which system produces the most enery Know the differences between photoautotrophys, chemoautotrophs, etc What is the electron transport chain, Where does this occur. Why is it more efficient than Glycolysis Know the differences between fermentation and respiration. What are other uses for the steps of respiration? Does it all go to energy Be able to define and explain the following terms Glycolysis Digestion Fermentation Role of Acetyl CoA Citirc Acid cycle (Main points) Glycolysis (Main Points) Chapter 6: Elements of Microbial Growth & Nutrition Microbial nutrition -What are the elements necessary for life -Which are macro or micronutrients -What are the sources of many of the Essential nutrients CNOPS, etch Different nutritional types (how do M.O.’s get their food) -Know what the different types are, how they get their food, examples of each.
