How Does Yeast Work?

Yeast ferments sugars by converting them into alcohol and carbon dioxide. This process is known as fermentation. Fermentation is an anaerobic process, which means that it does not require oxygen. Yeast cells use fermentation to produce energy.

Uses of Yeast

Yeast is used in the production of a wide variety of fermented foods and beverages, including bread, beer, wine, and yogurt. Yeast is also used in the production of biofuels and other industrial products.
