WebThe pyruvate generated through glycolysis enters the Kreb's cycle during the aerobic condition. Aerobic metabolism is the primary pathway that is slower but produces the maximum amount of ATP in the body. The two pyruvate molecules from glycolysis enter the citric acid cycle or Kreb cycle, and each molecule produces one ATP in one cycle. Web16 jun. 2024 · Pyruvate is the end product of glycolysis, which is converted into acetyl coA that enters the Krebs cycle when there is sufficient oxygen available. But when the oxygen is insufficient, pyruvate is broken down anaerobically, such as in fermentation that creates lactate or ethanol as an end-product.

"Web5 dec. 2024 · Without oxygen, the electron transport chain becomes jammed with electrons. Consequently, NAD cannot be produced, thereby causing glycolysis to produce lactic acid instead of pyruvate, which is a necessary component of the Krebs Cycle. Thus, the Krebs cycle is heavily dependent on oxygen, deeming it an aerobic process. " - How is pyruvate acid with the kreb cycle
