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. And the products are two pyruvates. Once again, because this takes place twice, we have four ATPs. So basically 1234, because it occurs twice.
