Does glycolysis occur during fermentation
WebApr 10, 2024 · Reprogramming energy production from mitochondrial respiration to glycolysis is now considered a hallmark of cancer. When tumors grow beyond a certain size they give rise to changes in their microenvironment (e.g., hypoxia, mechanical stress) that are conducive to the upregulation of glycolysis. Over the years, however, it has … WebB. Lactic acid fermentation can occur in microorganisms. C. Lactic acid fermentation can occur in certain tissues of animal bodies. D. NAD+ is regenerated during lactic acid fermentation for use in glycolysis. E. Lactic acid fermentation produces as much ATP per molecule of glucose as alcoholic fermentation.
