Lecture 14: Electron Transport Chain

 Topic

Reading

  • Electron Transport Chain
    • oxidation/reduction in the mitochondrial membrane
    • NADH to NAD+ = oxidation
    • oxygen to water = reduction
      • coupled reaction yields 52 Kcal/mole
    • Multistep process - move electrons down energy hill
      • use cytochromes
    • Chemiosmotic Theory
      • pump protons (oxidation.reduction)
      • create potential energy gradient
      • ATP phosphorylation
  • yield
    • 1 NADH yields 3ATP
    • 1 FADH2 yields 2 ATP
