Now along with releasing the carbon dioxide in step three, we also actually oxidize the six phosphaglucanate. And the molecule that picks up those electrons is once again the NAD plus molecule, NADP plus molecule. This is the oxidized version of nicotine amide adenine dinucleotide phosphate. So essentially we remove carbon one along with these two oxygens. So we form the carbon dioxide. In the process, we extract two electrons from the sugar molecule, place them onto this molecule.
