BL 424 2010 Cell Biology Quiz 1 50 pts name __________________________ 1. (8 pts) Matching cell structures. For each structure, indicate which of the organisms contain it. More than one choice may be written; choices may be used once, more than once or not at all. _______ nucleus A. Xenopus laevis _______ cell wall B. Saccharomyces _______ mitochondria C. Halobacterium _______ cell membrane 2. (5 pts) Matching compounds. Please indicate the category of each molecule. One choice each; choices may be used once, more than once or not at all. ______ glycogen A. carbohydrate ______ mRNA B. protein ______ RNase C. nucleic acid ______ phosphatidic acid D. lipid ______ cholesterol 3. (4 pts) Matching enzymes and function. One choice each; choices are used only once. ______ chymotrypsin A. synthesizes peptide bond ______ kinase B. cleaves peptide bond of proteins ______ ATP synthase C. adds phosphate to protein ______ phosphatase D. cleaves phosphate off of protein E. synthesizes ATP 4. (12 pts). Diagram clearly the structure of the phospholipid bilayer plasma membrane below. Indicate the cytoplasm and the outside of the cell. Be certain to include and clearly label: phospholipids, cholesterol, peripheral membrane proteins, And at least 3 integral membrane proteins (1 transmembrane, 1 only in outer face, 1 in inner).5. (9 pts) Metabolism. Consider the metabolism of glucose in an animal cell. Compare glucose metabolism by glycolysis, glycolysis + fermentation, versus oxidative respiration (products of glycolysis going through citric acid cycle and electron transport) Provide location of processes in cell, starting materials, end products and relative energy yield (do not forget NAD+/NADH). Location initial end relative Substrates products energy yield Glycolysis Oxidative Respiration (citric acid cycle; Electron transport) Glycolysis + fermentation 6. (6 pts) Briefly compare/contrast Brightfield microscopy versus Fluorescence microscopy, such as for what purposes each might be most useful. 7. (2 pts) Mitochondria and chloroplasts resemble bacteria in that they a. have their own DNA b. have their own ribosomes c. reproduce by simple division into two d. all of the above 8. (4 pts) For you, what was novel about this overview material? Briefly describe a new concept that you had not studied before, and that hasn’t been
