And so 1.5 ATP molecules are produced per single fadh two that is oxidized by the electron transport chain. And so because we have two of them, two multiplied by 1.5 gives us three. So to summarize, we have anywhere from two plus three, five to two plus five, seven ATP molecules produced from glycolysis. That includes the two ATP and the Nadhs that are basically oxidized by the electron transport chain. We have a net amount of five ATP produced by Pyruvate carboxylation when the Nadhs are oxidized by the electron transport chain and the total for the citric acid cycle. So we have two, three and 15, that's 20.
