Why does bread rise when yeast is added?
Yeast is added to bread along with moisture and sugar, and the dough is kept in a moist, warm environment. During this rising time, the yeast consumes the sugar in the dough and release CO2 gas, which is trapped in the dough and causes the dough to rise. When the dough is baked, the yeast is killed, but the bubbles created by the gas remain.
