In addition, we take an H plus I and place it onto this. And we form the ribulose phosphate molecule as well as another NADPH molecule. So the net amount of NADPH molecules that are formed when one glucose, six phosphate undergoes the first phase of the pentose phosphate pathway is two. One is formed in step one and the other one is formed in step three. So we have an enzyme called six phosphoglucanate dehydrogenase. Again, it's a dehydrogenase because we're essentially extracting the two H plus ions along with those two electrons which are picked up by this electron carrier molecule.
