How is pyruvate acid with the kreb cycle

Web14 mei 2024 · The reason the Krebs cycle is named as such is that one of its main products, oxaloacetate, is also a reactant. That is, when the two-carbon acetyl CoA … 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.
