In eukaryotes, pyruvate enters the mitochondrion and is oxidized to a compound called acetyl CoA, which enters the citric acid cycle (Krebs cycle.) In the third stage of respiration, the electron transport chain accepts electrons from the breakdown products of the first two stages (via NADH and FADH2).

First, pyruvate is converted to a two-carbon compound, acetaldehyde by the removal of CO2. Second, acetaldehyde is reduced by NADH to ethanol. Alcohol fermentation by yeast is used in brewing and winemaking. During lactic acid fermentation, pyruvate is reduced directly by NADH to form lactate (ionized form of lactic acid).

(Pyruvate oxidation results in one acetyl-CoA and one NADH – the acetyl-CoA will then enter the TCA cycle; the NADH will take the electrons to the electron transport chain) One “turn” of the TCA cycle for the acetyl-CoA will result in the production of 3 NADH, 1 FADH2, and one ATP (from substrate-level phosphorylation).

If O2 is present, the chemical energy stored in pyruvate and NADH can be extracted by pyruvate oxidation, the citric acid cycle, and oxidative phosphorylation. Concept 9.3 After pyruvate is oxidized, the citric acid cycle completes the energy-yielding oxidation of organic molecules
