Lecture 4.6 Competencies and Study Guide

Electron Transport Chain and OXPHOS

Vocabulary

  • Electron transport chain
  • Oxidative phosphorylation (OXPHOS)

Competencies

  1. Outline all three mechanisms of ATP production in cells that use oxygen.
  2. Explain the differences in the general purpose of the electron transport chain (ETC) and oxidative phosphorylation (OXPHOS).
  3. Name and describe the relationships of the protein complexes in the mitochondrial ETC.
  4. Identify the location in the cell of the ETC and OXPHOS.
  5. Explain the function of the ETC in general.
  6. Explain how the ETC uses free energy from redox reactions to make the mitochondrion into a battery.
  7. Explain what supplies the high energy electrons to the ETC.
  8. Explain why and how low energy electrons are oxidized off of the ETC.
  9. Explain how OXPHOS produces ATP.
  10. Explain the role of ATP synthase in this process.
