Electron transport

  1. 1. Electron transport
  2. 2. This ones not ad hard….but ill still explain it….b/c its kind of confusing….. :-/
  3. 3. • Electrons removed from glycolysis and the Krebs cycle are the first to enter by NADH • Takes placed in the mitochondria. • 1) NADH transfers e- to flavin mononucleotide.
  4. 4. 2) e- is than transferred to iron-sulfur protein.
  5. 5. 3) e- is transferred to ubiquinone.
  6. 6. 4) e- is carried between Q and oxygen, which is transferred to cytochrome (all cytochromes have heme (iron prosthetic group like that of hemoglobin) )
  7. 7. 5) e- is than transferred to iron-sulfur protein.
  8. 8. • 6) e- transferred to cyt-c1 => cyt-c => cyt-a => cyt-a3
  9. 9. 7) e- transferred to oxygen (1/2 O2) but also picks up a pair of hydrogen ions from the aqueous solution to form water.
  10. 10. Oxidative phosphorylation
  11. 11. • ATP is synthesized by ADP.
  12. 12. • Hydrogen ions than flow back down their gradient, due to ATP syntheses.
  13. 13. • The hydrogen ions continue to pass and making ADP transform into ATP.
  14. 14. • The final total is 34 ATP.
