The answer is pyruvate. In the absence of oxygen in
anaerobic respiration, the pyruvate is converted to lactic acid in animals and
ethanol in plants. However, in the presence of oxygen, the pyruvate enters the Krebs
cycle after being converted to Acetyl CoA. Pyruvate is an intermediate product
of glycolysis.
