So we bypass complex one. And so six protons total are pumped. And so six divided by four gives us 1.5. 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.
