Fermentation of glucose using yeast- Learn Chemistry

The resulting mixture is then tested for the presence of ethanol. The alcohol (ethanol) in beer and wine is produced by the fermentation of glucose by yeast. In this experiment, a glucose solution is left to ferment. The resulting mixture is then tested for the presence of ethanol. Type of Activity.
