    Anaplerotic reactions are those that form intermediates of a metabolic pathway. Anaplerotic reactions form intermediates for the Krebs, TCA, citric acid cycle. Two major types of anaplerotic reactions have been observed: 1.

  • Krebs Cycle - cliffsnotes.com

    Acetyl-CoA enters the Krebs cycle by combining with a four-carbon acid called oxaloacetic acid. The combination forms the six-carbon acid called citric acid. Citric acid undergoes a series of enzyme-catalyzed conversions. The conversions, which involve up to ten chemical reactions, are all brought about by enzymes.
