  2. Krebs cycle features and functions… fig 16-13

  3. O CH3-C O- O O CH3-C CH3-C it’s all about acetate… acetate acetyl group acetyl coenzyme A or acetyl-CoA S-CoA AcCoA rh

  4. all roads lead to acetyl-CoA… fig16-1

  5. electrons from acetyl groups fig16-1

  6. energy from electrons fig16-1

  7. This is HS-CoA, or CoA-SH, CoA, or coenzyme A fig16-3

  8. This is HS-CoA, or CoA-SH, CoA, or coenzyme A CoA-SH, or HS-CoA, or CoA fig16-3

  9. where the acetyl groups come from pyruvate dehydrogenase: PDH fig16-2

  10. Thiamine pyrophosphate (TPP): an activated carbon fig 14-13

  11. TPP as a carbanion nucleophile in pyruvate metabolism fig 14-13

  12. Lipoic acid cofactor of PDH E2 The “business end” of PDH fig16-4

  13. The PDH complex approx. 4.5 x 106 MW fig16-5

  14. The PDH complex fig16-5

  15. The PDH catalytic cycle oxidation of pyruvate fig16-6 (old)

  16. Several reactions, one basic location fig16-6

  17. Please read and LEARN “The Name Game”

  18. The: Krebs cycle citric acid cycle TCA cycle fig16-7

  19. Citrate synthase and its substrates… fig 16-8

  20. Getting fresh carbons into the act why it’s called the citric acid cycle pg 622

  21. making citrate asymmetric remember this for later… pg 622

  22. an iron-sulfer cluster in aconitase fig16-10

  23. electrons! NADH is the main carrier of Krebs cycle-derived electrons pg 624 (less fancy picture)

  24. more electrons! note CoA-SH has re-entered the picture pg 625

  25. direct production of a high energy phosphate but not ATP… instead it’s GTP pg 626

  26. direct production of a high energy phosphate but not ATP… instead it’s GTP pg 626
