1. Which of the following is common to both aerobic and anaerobicmicrobes? Fermentation An electron transport chain Pyruvate oxidation Glycolysis All of the above
2. The primary purpose of catabolism is generation of ADP. generation of ATP. oxidation of NADH to NAD+.
degradation of organic molecules. biosynthesis.
3. What is a fate of pyruvate during alcoholic fermentation byyeast? It is reduced to lactic acid. It is oxidized to form glucose and carbon dioxide It is cleaved to form acetylaldehyde and carbon dioxide. It is catabolized in glycolysis. It is oxidized to form lactic acid and carbon dioxide.
4. Electrons needed to reduce an oxidized electron acceptor areprovided by a) externally provided compounds such asH<sub>2</sub>, lactate or formate. b) an intermediate electron carrier such as NADH. c) 0<sub>2</sub>. d) Both a and b e) All of the above
5. How are aerobic respiration and anaerobic respirationsimilar? Both use oxygen as a terminal electron carrier. These are other names for glycolysis. Both utilize inorganic molecules as terminal electronacceptors. Neither receives electrons from glycolysis. Anaerobic respiration does not exist in microbes.
6. The conversion of phosphoenolpyruvic acid (PEP) topyruvate a) releases CO<sub>2</sub>. b) involves the conversion of ADP and ATP. c) involves substrate-level phosphorylation. d) Both a and b e) Both b and c
7. Which of the following is the best definition offermentation? The reduction of glucose to pyruvic acid The complete catabolism of glucose to CO2 andH2O
The oxidation of a carbohydrate with organic molecules servingas electron donors and acceptors The production of ATP from glucose The production of ethanol from glucose
8. A reaction that yields energy has a positive ?Go?. negative ?Go?. positive ?Eo?. negative ?Eo?. negative ?Ho?.
9. Oxidation and reduction reactions are always coupledbecause a) electrons generally accompany protons. b) protons generally accompany protons. c) electrons cannot exist free in solution. d) Both a and b e) All of the above
10. Which of the following is true of aerobic respiration? It involves the reduction of oxygen. It involves the oxidation of oxygen. It involves the reduction of lactic acid. It involves the oxidation of lactic acid. It does not generate ATP.
