is glycolysis oxidation or reduction
Rating Newest Oldest. Best Answer: First of all you have to know that Oxidation is the same as Dehydrogenation and reduction is the same as Hydrogenation. In the glyceraldehyde-3-phosphate a NAD takes an H and turns into NADH. The NAD has being hydrogenated (reduced). The glyceraldehyde-3-phosphate has lost an H so has being dehydrogenated (oxidized). So in the glycolysis you have 1 oxidation and 1 reduction.
