5. Energy can be extracted from glucose and converted to ATP only if: (Select all that apply.) A) oxygen is the electron acceptor. B) the cell has membrane proteins that can pump hydrogen ions. C) the cell has enzymes that can carry out oxidation-reduction reactions. D) the cell has enzymes that can carry out glycolysis. E) C and D 6. Cellular respiration is a series of -reactions. A) catabolic B) anabolic C) glycolytic D) phosphorylation E) carboxylation 7. In a thylakoid membrane, absorbed light energy is passed from one chlorophyll molecule to another until it is: A) dissipated as heat. B) released as fluorescence. C) passed to a reaction center. D) both dissipated as heat and released as fluorescence. E) All these choices are correct Which of the following statements is TRUE regarding aerobic respiration? A) 8. Aerobic respiration requires oxygen at every stage of the process. Aerobic respiration is carried out by all prokaryotes and eukaryotes. B) c) Aerobic respiration is a three-stage process, with oxidative phosphorylation comprising the last stage. D) Carbon dioxide is produced at every stage of aerobic respiration E) None of the other answer options is correct. Glycolysis results in the partial oxidation of glucose to pyruvate. This means that: A) glucose combines with oxygen in the cytoplasm to get partially oxidized. B) glucose donates electrons directly to NAD C) 9. glycolysis consists only of exergonic reactions so that ATP can be made from the release of energy the electron carriers donate electrons to proteins in the mitochondria that in turn produce ATP in the process of the conversion of glucose to pyruvate, some potential energy is transferred to NADH and ATP D) E) Page 2
