Is yeast the same as self raising flour?

Yeast and self-raising flour are not the same. Yeast is a live microorganism that is used as a leavening agent in baking. It converts the sugar in dough into carbon dioxide gas, which causes the dough to rise. Self-raising flour is a type of flour that already contains baking powder, a chemical leavening agent. Baking powder is a mixture of baking soda and one or more acids, such as cream of tartar. When baking powder is mixed with water, the acids react with the baking soda to produce carbon dioxide gas. This gas causes the dough to rise.

Self-raising flour is convenient to use because it does not require the addition of separate baking powder. However, it is important to note that self-raising flour is not the same as all-purpose flour. All-purpose flour does not contain baking powder, so it must be added separately when baking.
