And those electrons then move on to the groups found within complex three. And those electrons ultimately end up on cytochrome C. And as these electrons move, we see that a net result of four no two H plus ions actually flow from the matrix into the intermembrane space. And so far, we have four and two, that's six. And as the electrons are transferred from the cytochrome C on to complex four, we see that a net result of four ATP, four H plus ions are transferred into the intermembrane space. And so a total of four two and four. So ten H plus ions actually are transferred into the intermembrane space.
