And the thing about this shuttle is the high energy electrons produced by or found on the NADH produced in the glycolytic pathway ultimately end up being transported onto complex one. And complex one essentially pumps a net amount of four H plus ions into the intermembrane space. And so here we have four plus two plus four. That gives us a total of ten. And so ten divided by four gives us 2.5. And so what that means is the NADH molecules produced in glycolysis in cells that utilize the malade aspartage shuttle basically generate a net amount of 2.5 ATP molecules per single NADH that is oxidized by the electron transport chain.
