The yeast, a bacteria, eats up the sugars and produces carbon dioxide. That is the little bubbles you see and it asks as a leavening agent :)

Yeast is a microorganism, actually a type of fungus (yummy!). There are "wild" yeast spores floating around everywhere, all the time.
Baking yeast is simply a refined, cultured variety that's grown in a controlled environment, packaged and sold. Yeast leavens bread/pastries by consuming sugars (in the form of refined sugar, or in the form of carbohydrates in flour). The yeast excretes alcohol and carbon dioxide as waste products. In baking, the CO2 causes the rise. In beer making, both the CO2 and the alcohol contribute to the finished product.
