4:31 70 that is collected and stored in molecules of ATP. Here in the final stage of cellular respiration about 36 molecules of ATP are generated per molecule of glucose. Since the molecules of the electron transport chain require oxygen to function, this important last part of cellular respiration is an aerobic process.

6. Does anaerobic respiration and fermentation yield as much ATP as aerobic cellular respiration? Why or why not? Multiple choice (note questions may have more than one correct answer): 1. Where do the carbon atoms in pyruvic acid end up following the Krebs cycle? A. They enter the electron transport chain and make ATP B. They become part of a carbon dioxide molecule and end up in the atmosphere C. They join with citric acid to make Acetyl-CoA D. They build up in the intermembrane space 2. Which of the following are produced in the Krebs cycle? A. ATP B. NADH C. FADH2 D. CO2 3. The movement of which ion across the membrane causes ATP synthase to spin and make ATP. A. Na+ ions B. oxygen C. H+ ions D. water 4. Which stage of cellular respiration produces the most ATP? A. glycolysis B. Krebs cycle C. Electron transport D. Acetyl-CoA charging 5. Which of the following happens as electrons pass down the Electron Transport chain? A. Energy from the moving electrons transports H+ ions into the intermembrane space B. Carbon dioxide is released C. Energy from H+ ions crossing back into the matrix causes ATP synthase to make ATP. D. Water is produced

46. ATP is synthesized in the electron transport chain when which of the following moves across the inner mitochondrial membrane? a. NADH b. protons c. citric acid d. oxygen 47. Cellular respiration is essentially the reverse of what process? a. diffusion b. mitosis c. photosynthesis d. meiosis 48. The overall formula for cellular respiration is: a. C6H12O6 + 6 H2O -> 6 CO2 + 6 O2 + ATP b. 6 CO2 + 6 H2O -> C6H12O6 + 6 O2 + ATP c. C6H12O6 + 6 O2 -> 6 CO2 + 6 H2O + ATP d. none of the above 49. In figure 1, the reactions of the Krebs cycle would occur in which area? a. A b. B c. C 50. In figure 1, the electron transport chain would occur in which area? a. A b. B c. C

Oxidative phosphorylation is the final stage of cellular respiration and the main pathway of aerobic energy generation from glucose. Which of the following statements is NOT true? a. NADH and FADH2 are used as 'input' into the electron transport chain b. The electron transport chain produces a proton gradient across the inner mitochondrial membrane c. FADH2 stores less energy than NADH d. The electron transport chain is made up of several membrane protein complexes e. ATP synthesis by chemiosmosis requires about 30 protons per ATP molecule
