Guida verificata passo dopo passo1
Recall that glycolysis is the metabolic pathway that breaks down one molecule of glucose (a 6-carbon sugar) into two molecules of a 3-carbon compound.
Under aerobic conditions, glycolysis ends with the production of two molecules of pyruvate, which then enter the mitochondria for further oxidation in the citric acid cycle.
Under anaerobic conditions, pyruvate is converted into lactate in animals or ethanol in yeast, but these are not the end products of glycolysis under aerobic conditions.
Acetyl-CoA is produced after pyruvate is transported into the mitochondria and converted by the pyruvate dehydrogenase complex, so it is not a direct product of glycolysis.
Therefore, identify the end product of glycolysis per glucose molecule under aerobic conditions as two molecules of pyruvate.
