What is a common use for yeast, which is a type of fungi?

Yeast, a type of fungus, is widely recognized for its significant role in food production, specifically in the fermentation process. It is commonly used in baking and brewing, where it helps convert sugars into alcohol and carbon dioxide. In baking, the carbon dioxide produced by yeast causes dough to rise, creating a light and airy texture in bread and pastries. In brewing, yeast is essential for fermenting the sugars in grains or fruits to produce alcoholic beverages such as beer and wine. This fermentation process not only develops the flavors but also plays a critical role in the preservation of food products. Thus, the use of yeast in food making is a well-established and essential application in both traditional and modern culinary practices.
