The yeast consumes the sugars in the dough One of the by-products of this is CO2. As the CO2 is formed, it makes bubbles in the dough, and the bubbles continue to expand...this is what's happening as the dough is rising.

yeast eats the sugars in the bread dough and as a result they give off carbon dioxide gas as a by-product. This fills the bread with cO2 gas and makes it expand.

By converting the starch in the flour into carbon dioxide. The gas creates spaces in the bread.
