And once it binds it's able to actually interact with this substrate molecule. It polarizes this bond, weakens the bond and that's exactly what allows the Hydride to actually attack this carbon here and then allowing the H to go into this oxygen. And so ultimately we form ethanol and we regenerate that NAD plus. Now of course, because we form two Pyruvate molecules that means we have to multiply these two steps by two. And once we multiply these two steps by two and then we sum up all the processes, the ten processes of glycolysis and we sum these as well, this is the net equation that we get. And because we essentially regenerate that NAD plus, the NAD plus will cancel from both sides of the equation.
