The primary function of the Krebs cycle (also known as the citric acid cycle, or TCA cycle) is to complete the oxidation of carbohydrates, fats, and proteins, resulting in the formation of NADH and FADH2. These molecules carry high-energy electrons that are used by the electron transport chain to produce ATP through oxidative phosphorylation. The Krebs cycle also produces some ATP through substrate-level phosphorylation, but this is not its main function. Neither does it prime glycolysis for ATP production, nor produce H₂O and ATP.
