Krebs Cycle and Electron Transfer Chain

Krebs Cycle:

• Acetyl co-enzyme A reacts with a 4 carbon compound molecule to form a 6 carbon molecule that enters the Krebs Cycle 
• Co-enzyme A is recycled to the Link reaction
  • in a series of oxidation / reduction reactions
  • reduced co-enzymes are produced
• ATP is produced by substrate level phosphorylation
• Carbon dioxide is lost (Carbon atom number goes down)

For each multiple of glucose, Krebs Cycle generates:

• 4x carbon dioxide production by decarboxylation
• 6x NADH produced by redox reactions
• 2x FADH2 produced by redox reactions
• 2x ATP produced by substrate level phosphorylation
