1. If enzyme is added to a .3 M solution of fructose 6 phosphate and reaction is allowed to proceed to equilibrium, final concentration is .2M glucose 6 phosphate and .1M fructose 6 phosphates what is equilibrium constant? 2 2. Specialized Cellular appendages of prokaryotes that help bacteria adhere to one another when they exchange gene info are called---pili 3. Cilia---Are shorter and more numerous than flagella 4. Large organelle shown below is----nucleus 5. Components of chloroplasts include---granum and thylakoids 6. Plant and animal cells are similar in appearance. One difference is that only animal cells contain Centrioles. 7. Of the following plant structures, which is most likely to have the greatest volume—vacuole. 8. Which of the following is not an argument for endosymbiotic theory?— mitochondria and chloroplasts cannot be grown in culture, free of a host cell. 9. How does the surface area to volume ratio of a 1 mm cube compare to the surface area of a 3 mm cube?—The ratio decreases as the cube becomes larger. 10. In the presence of alcohol dehydrogenase, the rate of reduction of acetaldehyde to ethanol increases as the concentration of acetaldehyde is increased. Eventually the rate of the reaction reaches a maximum, at which further increases in concentration of acetaldehyde have no further effect, why is this?--- all the alcohol dehydrogenase molecules are bound to the acetaldehyde molecules. 11. The overall shape of an animal cell is determined by its-----cytoskeleton 12.The membrane surrounding each organelle---regulates traffic into and out of the cell. 13. Of the following structures in the animal cell, the one with the largest volume is---nucleus

14. The DNA of prokaryotic cells is found in the-- nucleoid region 15. Lysosomes are important to eukaryotic cells because they contain---digestive enzymes 16. What is purpose of inner folds of inner mitochondrial membrane---they increase surface area for the exchange of substances across the membrane 17.
