The ingredients in bread dough (flour, water, yeast, and sugar) interact to make the bread dough rise. Here's how it works: The water activates the yeast. The yeast then feeds on the sugar. The yeast produces carbon dioxide gas—a waste product—that gets released into pockets in the dough. As gas continues to accumulate, these pockets continue to expand. This expansion causes the bread dough to rise.
