Now let's move on to Pyruvate carboxylation. So this process does not form ATP molecules directly but it forms two NADH molecules. And remember, a single NADH molecule formed in the mitochondrial matrix produces three ATP molecules on the electron transport chain. So we have two multiplied by three each. So we have six ATP molecules. So we have a total of six ATP molecules formed indirectly as a result of pyruvate decarboxylation.
