What is the result of the process of fermentation in yeast?

• A. Glucose and oxygen
• B. Carbon dioxide and water
• C. Ethanol and carbon dioxide
• D. Lactic acid and energy

Answer: (C)

Fermentation in yeast primarily converts glucose into ethanol and carbon dioxide through a series of biochemical reactions. This anaerobic process occurs when yeast lacks sufficient oxygen to undergo aerobic respiration. During fermentation, glucose is broken down through glycolysis, producing pyruvate, which is then converted into ethanol and carbon dioxide by enzymatic action. This process not only allows yeast to generate energy but also contributes to the production of alcoholic beverages and the leavening of bread through the carbon dioxide gas released. Overall, the main products of fermentation in yeast are ethanol, which is used in various alcoholic products, and carbon dioxide, which is responsible for the rise in dough and the bubbles in beer.
