-1-BIOS 100 - Summer, 2010 Name:Exam II, 16 July, 2010Michael Muller, Instructor TA:This exam consists of 52 questions. As always, choose the best answer for each question. Goodluck!The dreaded “what makes what” section. Use the key below to answer questions 1 through 6.I. Glycolysis V. Alcohol FermentationII. Oxidation of Pyruvate VI. Lactic Acid FermentationIII. Krebs Cycle VII. Non-cyclic PhotophosphorylationIV. Oxidative Phosphorylation VIII. Cyclic PhotophosphorylationIX. Calvin-Benson Cycle1. How many of the above processes produce energy molecules in the form of ATP, NADH,2NADPH, and/or FADH ?A. Four B. Five C. Six D. Seven E. Eight2. In which of the above processes do you see the electron with the greatest energy?A. I only B. VII only C. VIII only D. VII, VIII E. None of the above3. In which of the above processes is NAD regenerated?+A. I, II, III B. IV only C. V only D. V, VI E. IV, V, VI4. In which of the above processes is NADP regenerated?A. VII only B. VII only C. VII, VIII D. IX only E. VII, VIII, IX25. How many of the above processes produce CO ?A. One B. Two C. Three D. Four E. Five6. How many of the above processes have a net consumption of ATP?A. One B. Two C. Three D. Four E. Five7. A small acorn over time can grow into a huge oak tree. The wood in such a tree can weighmany tons, even after it has been cut into logs and dried. Where does most of thisbiomass (dry mass) come from as the tree grows?A. Minerals in the soil B. Organic matter in the soil C. The air D. SunlightE. None of the above8. Right now, where is the majority of ATP being produced in the plants outside at the UICcampus?A. In the mitochondria B. In the chloroplast C. In the cytoplasmD. In the nucleus E. None of the above9. Non-cyclic photophosphorylation is:A. Endothermic B. Exothermic-2-10. DCMU is chemical that prevents electron flow of the plastoquinone in the electron transportchain of the chloroplast (i.e. plastoquinone cannot accept electrons). What will be theimmediate effect of the application of DCMU on a plant?A. Nothing, the plant has biochemical pathways which can circumvent the blockedplastoquinonesB. Non-cyclic photophosphorylation will be blocked, but cyclic photophosporylation willbe unaffectedC. Cyclic photophosphorylation will be blocked, but non-cyclic photophosporylation willbe unaffectedD. Both cyclic and non-cyclic photophosphorylation will be blockedE. None of the above11. What will be the long-term effect on the plants?A. The plants will survive just fine - they will be indistinguishable from non-treated plantsB. The plant’s growth will be stunted and they will probably look sickly, but most will liveC. The plants will die much sooner than non-treated plants12 Which of the following statements (A-D) about ATP production in plants is FALSE? Ifstatements A-D are TRUE, then choose E.A. Plant cells can generate ATP in their cytoplasm, the chloroplast, and the mitochondriaB. The amount of ATP generated in the light-dependent reactions in C3 plants isgreater than the amount of ATP generated in the light-dependent reactions inC4 plants.C. At midnight, most of the ATP production in plant cells occurs in the mitochondriaD. ATP synthesis in both the mitochondria and the chloroplast is powered by thepotential energy generated by proton pumpsE. All of the above statements about ATP production in plants are TRUE.13. Which of the following statements (A-D) about photorespiration is FALSE? If statementsA-D are true, then choose E.A. Photorespiration is bad for the plant (I will be very upset if you choose this one...)B. The phosphoglycolate produced by photorespiration has no use in the plantC. Photorespiration is more commonly seen in C4 plants than C3 plantsD. Repairing the damage caused by photorespiration can cost the plant up to 40% of itstotal net photosynthetic gainE. All of the above statements are TRUE14. Where in the electron transport chain of the mitochondria does the electron have the leastenergy?2A. When it is bound to NADH B. When it is bound to FADHC. When it is bound to Complex I D. When it bound to Complex IIE. When it is bound to water15. A glyceride has three fatty acid chains, each containing six carbons. When this glyceride isbroken down in beta oxidation, the glycerol will be converted to a single Acetyl CoA. How many additional Acetyl CoAs will be formed by the three fatty acid chains?A. Three B. Six C. Nine D. Twelve E. Eighteen-3-16. When water is split by the p680 (PSII) complex, we say that the water molecule is:A. Oxidized B. Reduced C. None of the above17. Which process produces the most ATP?A. Oxidation of pyruvate B. Krebs Cycle C. GlycolysisD. Oxidative phosphorylation E. Lactic Acid Fermentation18. What purpose does fermentation serve in biological systems?A. Under aerobic conditions, it drives the formation of acetyl CoA, which then feedsinto the citric acid cycle.B. It allows for the production of NADH, which keeps the electron transport chain going.C. It regenerates NAD+ from NADH to keep glycolysis going in the absence of oxygen.D. It produces an abundance of ATP when oxygen is absent.2E. It produces produce CO which yeast can use in their chloroplasts19. In phosphofructokinase, the active site has a much higher affinity for ATP than theregulatory site does. Which answer best summarizes what the consequences would be ifthe regulatory site had a much higher affinity for ATP than the active site did?A. Glucose oxidation would occur faster at low ATP concentrations.B. Glucose oxidation would be inhibited even if ATP were scarce in the cell.C. Glucose oxidation would be inhibited only at high ATP concentrations.D. Glucose oxidation would occur via a completely different metabolic pathway. 20. Which of the following comparisons between components of aerobic respiration andphotosynthesis is FALSE?A. The light-dependent reactons of photosynthesis breaks a water molecule to produceoxygen gas and ultimately give that electron to an electron carrier molecule (NADPto produce NADPH) while respiration takes electrons from electron carrier2molecules (NADH and FADH ) and ultimately donates them to oxygen gas toproduce waterB. Both aerobic respiration and photosynthesis synthesize ATP through the generation ofH gradients via electron transport systems+C. Both photosynthesis and aerobic respiration have a net production
