"Citric acid cycle (tricarboxylic acid cycle, TCA cycle, Krebs cycle) is a series of chemical reactions used by all aerobic organisms to generate energy through the oxidation of acetate derived from carbohydrates, fats and proteins into carbon dioxide and chemical energy in the form of adenosine triphosphate (ATP)." [Citric acid cycle. Wikipedia]
This biochemical diagram example shows metabolic pathways map of citric acid cycle reactions.
