And so three ATP molecules will be formed per two NADH molecules produced in glycolysis in cells that utilize the g three P shuttle to actually move the NADH onto the electron transport chain. So where do we get that number? Well, when the two electrons from NADH are ultimately transported onto complex three, we know that complex three of the electron transport chain actually moves a net amount of two H plus ions. And so actually, we're moving them from the matrix into the intermembrane space so it's in this direction. And then when the electrons are moved on to this particular complex, complex four, we move a net quantity of four H plus. And so we basically create a proton gradient where we move six H plus ions.
