Yeast is used in the baking of bread because it feed on fermented sugars and releases bubbles of carbon dioxide. This causes the dough to rise in the form of bubbles and when the yeast dies, the gas left behind forms a soft sponge like texture, which gives the bread its shape. This is called fermentation and also in the process, other products such as alcohol and acids are released, which end up giving the bread different aromas and tastes.
