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. So that does not appear in this equation. And so the net equation of glycolysis following fermentation, specifically ethanol fermentation, this is our net equation. So a glucose goes in.
