Biol. 1001 Jonathan Morris 639173 Lesson 5: How Cells Harvest Chemical Energy 1) Write the formula for cell respiration. Why is energy harvested in many small steps instead of one or two large ones? Hint: think of second law of thermodynamics 2) Construct a chart to compare and contrast the two methods of forming ATP. What are the benefits of each? 3) Write out two different redox reactions in cell respiration. Indicate which molecules have been oxidized and which have been reduced. 4) Cell respiration has three parts: Glycolysis, the Krebs cycle, and the electron transport chain. Tell where in the cell each is found, the molecule(s) that enter each, the molecules at the end of each, and the amount of ATPs harvested from each. 5) Poisons often work at the cellular level. Choose rotenone, cyanide, of carbon monoxide and explain how they kill. 6) What are NAD and FAD? How do their roles differ? Which is found in greater amounts? 7) Explain why the wine maker was so upset when his son lifted the lids on the vats of fermenting grapes.
