Citric acid krebs cycle definition
WebIn the process, citric acid is converted to its isomer isocitrate. Step 3 Isocitrate loses a molecule of carbon dioxide (CO2) and is oxidized forming the five-carbon alpha ketoglutarate using isocitrate dehydrogenase. WebJan 16, 2024 · The Krebs cycle is a typical example of an amphibolic pathway because it works both in the degradation and synthesis processes. The citric acid cycle or Krebs cycle plays a vital role in cellular respiration. The Krebs cycle takes place on the cytosol of bacteria and within the mitochondria of eukaryotic cells.
