Study Guide for Exam 3 – MMG 301 Fall 2006 MMG 301 Summer 2006 Study Guide for Lectures 20-30 Respirations and Photosynthesis [Lecture 20] Vocabulary : terminal electron acceptor, electron transport phosphorylation, electron transport chain, electron tower, oxidative phosphorylation, ATP synthase, adenosine 5’-phosphosulfate, oxygenic and anoxygenic photosynthesis, accessory pigments, carotenes, phycobilins, heterocyst Concepts : recall that membranes required for respiration; review comparison of fermentation and respiration two substrates required for respiration (one oxidized and the other reduced) anaerobic respiration uses electron acceptors other than O 2 – what are some examples review the general schemes of electron transport pathways and not the individual electron carriers review chemoorganotrophic and chemolithotrophic respiration; what is the carbon source for each; how can microbial respiratory reactions be used for production of electricity? how much more energy is produced from aerobic respiration of glucose compared to fermentation how does Pseudomonas stutzeri efficiently carry out anaerobic respiration of nitrate how is carbon dioxide utilized by methanogens and acetogens review the 4 groups of photosynthetic bacteria how can organisms using bacteriochlorophyll a co-exist with organisms that use chlorophyll a without significant competition for light energy briefly review oxygenic (Z scheme with 2 photosynthetic reaction centers) and anoxygenic (one photosynthetic reaction center) photosynthesis; how is ATP generated Vocabulary : bacteriophage, capsid, enveloped virus, capsomers, nucleocapsid, lysis, plaque, lysogen; induction, complex virus, polyprotein, segmented genome, antigenic shift, oncogene, homologous, Holiday junction, heteroduplex DNA, mutation, competence, conjugation, pilus, Hfr, IS sequences, oriT , gene, transposon, complementation, inversions, translocations, reversions Concepts : what are the general structural differenced between filamentous, icosahedral, and complex viruses what is a virus “titer” and how is it determined review the life cycle of the T4 bacterial virus; how are viral components made when they are needed; the T phages are lytic; lambda can be lytic or lysogenic what are the two paths that an E. coli cell can take after it is infected with lambda; what is induction what human cancers are associated with what viruses what are the significant features of influenza virus (type of genome, envelope proteins, antigenic shift) what replication enzyme is a distinguishing feature of retroviruses; what are the three major gene regions in retroviruses; note some retroviruses also possess oncogenes review retrovirus life cycle, how is the envelope formed as the virion exits the cell; why are protease
