And so ultimately, those two electrons on the NADH produced in the glycolytic pathway actually end up on this protein, and then they're picked up by Ubiquinone to form Ubiquinol. And so NADH bypasses complex one. And that means as the electrons pass down to Ubiquinol, the Ubiquinol travels and attaches onto complex three. And so now two protons are pumped here, four protons are pumped here. So we form a net result of six protons in this case as compared to the ten protons in the previous case. And so now six H plus ions divided by we still need four H plus to generate a single ATP.
