Now, once the NADH molecule is formed in the process of glycolysis, it remains in the cytoplasm. And what happens to it is a special enzyme known as cytoplasmic. Glycerol three phosphate dehydrogenase actually oxidizes the NADH back into NAD plus. That regenerates the NAD plus coenzymeter for glycolysis. And what this process also does is it passes those high energy electrons from the NADH onto a molecule known as DHAP, dihydroxy acetone phosphate. And this is the same molecule that we find as an intermediate in the glycolytic pathway.
