Fermentation:This process involves breaking down sugars into simpler substances such as alcohol or lactic acid. Yeast uses this process to produce ethanol from glucose.
Yeast: These are single-celled fungi that reproduce rapidly and play an important role in baking and brewing due to their ability to ferment sugars into carbon dioxide and alcohols.
Glucose:A simple sugar molecule which serves as the main source of energy for cells. It's the starting point for fermentation in yeast, which results in ethanol and carbon dioxide.
