Krebs Cycle

• Krebs cycle

  A series of redox reactions
• For each glucose molecule the cycle will go around twice
• Citrate is a six carbon molecule and is formed from oxaloacetate and acetyl with Coenzyme A returning to the link reaction
• citrate is converted to a 5 carbon molecule with waste of CO2 and reduced NAD which enters the final stage
• The 5C is then converted back to the 4C compound oxaloacetate which can be used again this happened through a number of intermediate compounds during this process carbon dioxide is produced, 2 molecules of reduced NAD, 1 molecule of reduced FAD and 1 molecule of ATP
• When a phosphate group is directly transferred from one molecule to another it is known as substrate level phosphorylation
• Krebs cycle
