And so instead of forming this final product, this molecule will be 100 times more likely to go on and form this molecule here. That's why it's so important that this enzyme is actually here, because in the absence of this enzyme, this DHAP, would go on to form the nodiol intermediate, but then the nodiol intermediate would be 100 times more likely to go on and form this product, which we actually don't want to form. And so what this enzyme does is it basically stops these competing reactions from actually taking place. And the way that it stops them is it places this molecule into this active side, into this perfect environment in which these catalytic residues can actually interact and promote this specific type of reaction. And that's why we need this trio's phosphate isomerase in the cell, because it's the molecule that can very quickly and rapidly transform this molecule, die hydroxy acid phosphate, into the molecule that we want. So the glycero aldehyde three phosphate.
