Presentation Transcript

  1. Link Reaction and The Citric Acid Cycle. Link Reaction

  2. The Link Reaction or Transition Reaction(named this because it links glycolysis to the Krebs/Citric Acid cycle).

  3. Citric Acid/Krebs Cycle(see Fig 8.8 and 8.9 in text)

  4. 1. First reaction: 2. Decarboxylation reactions:

  5. 3. Oxidation reactions: 4. Substrate-level phosphorylation reactions:

  6. Number of yielded molecules worth mentioning so far (Glycolysis, Link Reaction, and Citric Acid Cycle) that came from one glucose molecule. • Glycolysis 2 NADH + H+ 2 ATP • Link reaction (remember there are 2 pyruvates that enter this reaction) 1 NADH (x2) = 2NADH 1 CO2 (x2) = 2CO2

  7. Citric Acid/Krebs cycle (remember there are 2 Acetyl-CoA that enter this cycle) 2 CO2 (x2) = 4 CO2 3 NADH (x2) = 6 NADH + H+ 1 FADH2 (x2) = 2 FADH2 1 ATP (x2) = 2 ATP
