Cards (9)

  • Takes place in the matrix of the mitochondria.
  • Requires oxygen.
  • Pyruvate converted to Acetyl which combines with Coenzyme A (2C) (end of glycolysis)
  • Acetyl CoA combines with oxaloacetate a 4C compound to form citrate (6C).
  • Citrate is converted back to oxaloacetate by a series of enzyme controlled reactions.
  • During the cycle, carbon is released in the form of carbon dioxide,
    hydrogen is released and binds to NAD and ATP is formed.
  • Dehydrogenase enzymes remove hydrogen ions and electrons which are passed to the coenzyme NAD to form NADH.
  • This occurs in both in glycolysis and the citric acid pathways.
  • NADH releases electrons to the electron transport chain on the inner mitochondrial membrane (cristae).
