Yeast makes ethanol to prevent metabolic overload

Why do some yeast cells produce ethanol? Scientists have wondered about this apparent waste of resources for decades. Now, University of Groningen scientists think they have a solution: yeast cells produce ethanol as a 'safety valve' to prevent overload when their metabolic operation reaches a critical level. The new theory, which was published in Nature Metabolism on 7 January, could have far-reaching implications, as it also explains why cancer cells waste energy by producing lactate, known as the Warburg effect.
