So now let's count up all the reactants and all our products. So the reactants are basically the glucose. So we also have two ATP molecules, one and two that have to be utilized. We have four ATP molecules, so we have one, two, and because it takes place twice, we have four ADP molecules. We have one because it takes place twice, we have two PiS phosphates, we have two NAD pluses because this takes place twice. And we have two H pluses, which I haven't shown in these steps.
