2. In aerobic respiration, what becomes the final electron acceptor in the making of energy?
a. Oxygen b. Carbon dioxide c. NADP d. ATP
3. What is the major difference between fermentation and anaerobic metabolism?
a. Glycolysis is not a part of fermentation. b. Pyruvate is not a part of glycolysis but is a part of fermentation. c. ATP is not generated in fermentation. d. There is no Krebs cycle used in fermentation.
4. Where does glycolysis take place in the cell?
a. Ribosomes b. Nucleus c. Cytoplasm d. Mitochondria
5. What molecule is the end-product of the first phase of glycolysis?
a. Glyceraldehyde-3-phosphate b. Citric acid c. Pyruvate d. Acetyl-CoA
6. Which is the function of an isomerase enzyme?
a. It cleaves a molecule into two parts. b. It adds a hydrogen ion to a molecule. c. It dephosphorylates a molecule. d. It rearranges atoms on a molecule.
7. Why might a given cell perform anaerobic respiration instead of aerobic respiration?
a. It does not have enough glucose to metabolize. b. It cannot perform the transition to make acetyl CoA from pyruvate c. It does not have enough Krebs cycle enzymes to turn acetyl-CoA into CO2. d. It does not have cytochrome oxidase to pass electrons to oxygen.
8. In prokaryotic enzymes, how does the electron transport system get used?
a. Electrons get transferred through an electron transport system, so hydrogen ions get pumped out of the cell. b. Electrons get transferred through an electron transport system, so hydrogen ions get pumped into the cell. c. As protons get transported through the electron transport system, electrons get pumped out of the cell. d. Protons get transported through the electron transport system, so electrons get pumped into the cell.
9. What is the end product of the light-dependent reactions in photosynthetic cells?
a. NADH b. ATP and NADPH c. Carbon dioxide d. Oxygen
10. What is made in the Calvin cycle as its end-product?
a. Glyceraldehyde-3-phosphate b. Carbon dioxide c. ATP d. NADH
