41. In the reactions of glycolysis shown below what is the “electron carrier molecule” that is being reduced? (This is the molecule that will run the Electron Transport Chain) 

50. If an organism is only capable of undergoing fermentation, what is the maximum number of ATP it can produce per run of fermentation (ie. glycolysis)?

5. Which of the following proteins are NOT synthesized on bound ribosomes bound to the Rough ER? 

3. A mycoplasma is a single celled organism with a diameter between 0.1-1.0 µm (micrometers). What does its size tell you about how this organism might be classified?     

25. Babies receive disease-fighting antibodies (large protein molecules) while nursing their mother’s milk.  These large protein molecules most likely enter the cells lining the baby’s digestive tract by which of the following methods?

55. Most of the atmospheric O2 on the planet today is a result of photosynthesis. Oxygen is released when which of the following molecules is oxidized during the light reactions of photosynthesis?        

12. The chemical Cyanide is toxic because it binds with molecules involved in ATP production and inhibits their activity.  Based on this, following exposure to cyanide where would you expect to find cyanide concentrated in a cell?

50. If an organism is only capable of undergoing fermentation, what is the maximum number of ATP it can produce per run of fermentation (ie. glycolysis)?

35. Which of the following best depicts an interaction between enzymes and substrates (reactants)? (E = Enzyme, S = Substrate, ES = Enzyme-Substrate Complex, P = Products)

59. The reactions of the Calvin Cycle of Photosynthesis are shown below. Where do these reactions occur?
