WebThe TCA cycle is named for tricarboxylic acids (TCA) because citric acid (or citrate) and isocitrate, the first two intermediates that are formed, are tricarboxylic acids. Additionally, the cycle is known as the Krebs cycle, named after Hans Krebs, who first identified the steps in the pathway in the 1930s in pigeon flight muscle. Citric Acid Cycle WebApr 20, 2024 · When glucose is chemically "burned" as a fuel to produce carbon dioxide (CO 2) and water (H 2 O), the energy released from this oxidation process is 670 kcal/mol of glucose: C 6 H 12 O 6 + 6 O 2 → 6CO 2 + 6 H 2 O ΔH = -670 kcal/mol. The net energy yield from anaerobic glucose metabolism can readily be calculated in moles of ATP.
