WebPyruvate oxidation steps. Pyruvate is produced by glycolysis in the cytoplasm, but pyruvate oxidation takes place in the mitochondrial matrix (in eukaryotes). So, before the chemical reactions can begin, pyruvate … WebStep 2. The hydroxyethyl group is oxidized to an acetyl group, and the electrons are picked up by NAD +, forming NADH (the reduced form of NAD+). The high- energy electrons from NADH will be used later by the cell to generate ATP for energy. Step 3. The enzyme-bound acetyl group is transferred to CoA, producing a molecule of acetyl CoA.
