Glycolysis The inset indicates the relationship f fermentation to the overall (a) int step is glycolysis,the con- enion of glucose to pyruvic acid. n the second step,the redueed (NADH.NADPH) ctro and hydro en iom to pyruvie acid or a erivative to form a fermentation d-product.(b)End-products of nous microbial fermentations. n fermentation,ATP is gener- ted only during glycolysis.
