What is what does yeat mean?

Yeast is a type of fungus that is widely used in the baking and brewing industry. Yeast can be found in different forms, including fresh, dry, or instant. The most commonly used yeast in baking is the Saccharomyces cerevisiae strain, which ferments sugar to produce carbon dioxide and alcohol, causing dough to rise and become light and fluffy. Yeast is also important in brewing as it converts sugar into alcohol during the fermentation process. Apart from food, yeast also has many other uses, such as in the production of biofuels, pharmaceuticals, and enzymes.
