How can yeast be used in cooking to enhance the flavor and texture of bread and other baked goods?

Yeast is a microorganism that helps bread and baked goods rise by producing carbon dioxide gas through fermentation. This process creates air pockets in the dough, resulting in a light and fluffy texture. Additionally, yeast adds a unique flavor to the baked goods as it breaks down sugars in the dough. Overall, yeast is essential in baking to improve the taste and texture of bread and other baked goods.
