Post by: kfurse on Jul 15, 2019

When an organism such as a yeast lives by fermentation, it converts the pyruvate from glycolysis into a different compound, such as alcohol. Why doesn't it secrete the pyruvate directly?
◦ The conversion is needed to regenerate the molecules needed for glycolysis.
◦ The conversion yields 1 NADH per pyruvate molecule.
◦ The conversion yields 32 ATP per pyruvate molecule.
◦ A buildup of pyruvate in the surrounding environment would be too toxic.
