Answer:

The gas molecules responsible for the increase in dough size are carbon dioxide.

Explanation:

Yeast feed of sugars by braking them into carbon dioxide, alcohol, other molecules, and energy. This process is known as fermentation. When fermentation occurs, carbon dioxide expands, helping the bread dough to increase. Yeast is also important to produce alcohol and gluten, both important to bake bread.
