And so we transform the six phosphorlucano delta lactone into a six phosphoglucanate molecule. We also release the H plus ion as shown here. So once we open up this molecule, it's now ready to undergo a decarboxylation reaction. 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.
