  1. ELECTRON TRANSPOT CHAIN REVIEW ENTER

  2. This module will help you review the Electron Transport Chain (ETC) introduced in your Metabolism I course. To review the material click on “Resources” at anytime during the review. RevIEW Resources

  3. Click on the content area that you would like to review. What WOULD YOU LIKE TO REVIEW? Resources Components Functions Processes Outputs Exit

  4. Given a diagram, you will be able to drag the name of the component and drop it on the correct component. You will also be able to identify which ETC components are proton pumps. Components Resources

  5. Click on a part of the ETC below and drag it to the correct label. Do this for each. Resources NADH dehydrogenase Complex Ubiquinone Inner Membrane of the Mitochondria Cytochrome b-c complex Try again ATP Synthase Done Cytochrome C Cytochrome oxidase Next

  6. Click on a part of the ETC below and drag it to the correct label. Do this for each Resources NADH dehydrogenase Complex Inner Membrane of the Mitochondria Ubiquinone Cytochrome b-c complex Try again ATP Synthase Done Cytochrome C Cytochrome oxidase Next

  7. Which of the following is not a Proton Pump? Click on the correct answer. COMPONENTS Resources Incorrect Complex I Correct Complex II Incorrect Complex III Incorrect Complex IV

  8. All complexes of the Electron Transport Chain are embedded in the: COMPONENTS Resources Incorrect intermembrane space of the mitochondria Incorrect mitochondrial matrix Correct mitochondrial inner membrane Incorrect mitochondrial outer membrane 

  9. You have now reviewed the components of the ETC. Choose another aspect of the ETC to review or re-review this section. COMPONENTS Resources Components Functions Processes Outputs Exit

  10. In this section you will be able to identify the functions of some components shown below, given different options. FUNCTIONS Resources

  11. The function of complexes I, III, and IV is to: FUNCTIONS Resources Incorrect maintain a higher concentration of protons in the outer mitochondrial space Correct maintain a higher concentration of protons in the inter mitochondrial space Incorrect transport electrons from the outer mitochondrial space to the inner mitochondrial space Incorrect transport electrons from the inner mitochondrial space to the outer mitochondrial space 

  12. The function of cytochrome C is: FUNCTIONS Resources Incorrect The transfer of electrons from complex I to complex III Incorrect The transfer of electrons from complex IV to ATP synthase Incorrect The pumping of protons from complex III to complex IV  Correct The transfer of electrons from complex III to complex IV

  13. You have now reviewed the functions of the ETC. Choose another aspect of the ETC to review or re-review this section. FUNCTIONS Resources Components Functions Processes Outputs Exit

  14. In this section you will be able to identify some the processes shown, given different options. Processes Resources

  15. What two processes, when coupled together, result in ATP production? Processes Resources Incorrect hydrolysis, condensation Incorrect transformation, reduction  Incorrect peroxidation, reduction Correct oxidation, phosphorylation

  16. If the processes of oxidation and phosphorylation were uncoupled, a result would be: Processes Resources Correct heat given off Incorrect increased ATP production Incorrect more water produced Incorrect the proton concentration gradient would be maintained 

  17. You have now reviewed the prcoesses of the ETC. Choose another aspect of the ETC to review or re-review this section. Processes Resources Components Functions Processes Outputs Exit

  18. In this section you will be able to identify the amount of different outputs of the ETC, given different options. OUTPUTS Resources

  19. When hydrogen atoms enter the electron transport chain from FADH2, what is the maximum number of ATP which could be generated? Enter your answer. OUTPUTS Resources Incorrect 1 Incorrect 2 Correct 3 Incorrect 4

  20. When hydrogen atoms enter the electron transport chain from FADH2, what is the maximum number of ATP which could be generated? Enter your answer. OUTPUTS Resources Incorrect 1 Correct 2 Incorrect 3 Incorrect 4

  21. You have now reviewed the outputs of the ETC. Choose another aspect of the ETC to review or re-review this section. Outputs Resources Components Functions Processes Outputs Exit

  22. Wikipedia ETC Video RESOURCES

  23. How did you do? Return to this review module as often as you like! Knowledge about the components, functions, processes, and outputs of the ETC will help you understand human metabolism. Here is more information on how to apply these concepts. Review at your leisure Resources
