In this lab, you will try to determine whether yeast are capable of metabolizing fermentation. The formula for the yeast fermentation reaction is: C 6H 12O 6 = 2CH 3 CH 2 This shows that fermentation is happening! Yeast fermentation is a biological process where yeast converts sugars into alcohol and carbon dioxide (CO₂) in the absence of oxygen. In cellular respiration and in alcohol fermentation, carbon dioxide gas is given off as a product. Save. With fermentation, yeast can still get energy from sugar, but less energy is derived from each sugar molecule. Yeast is a fungal microorganism that man has usedsince before he had a written word. Submit Search. The organisms in the Kingdom Fungi are not capable of making their own food. Fermentation is sped up by a small amount of sugar, up to 3%. Even to this day, it remains a common component of modern beer and bread Fermentation of Glucose by Yeast: Lab Explained.
