It usually gives off carbon-dioxide. It is why u sometimes see little holes or bubbles where the gas gathered.

While bread dough is proofing, it ferments and produces gas pockets, which are the holes that you see.
Air spaces form in bread during the baking process due to the release of carbon dioxide gas produced by yeast as it ferments sugars in the dough. This gas becomes trapped in the gluten structure of the dough, causing it to expand and creating pockets of air in the final bread product.
Yes, in the presence of sugar, yeast ferments releasing carbon dioxide (which makes the bubbles in bread dough).
Yeast is a microorganism that helps bread dough rise by fermenting sugars and producing carbon dioxide gas. This gas creates bubbles in the dough, making it light and fluffy. Yeast also adds flavor to the bread as it ferments.
Leavening means to put something into dough which ferments and causes the dough to rise. The most commonly used leavening is yeast.
Carbon dioxide
carbon dioxide is he gas excreted by yeast metabolising sugars in the dough making it rise.
Humans use fermentation for various purposes such as producing alcoholic beverages like beer and wine, baking to make bread rise, pickling to preserve vegetables, and producing dairy products like yogurt and cheese. Fermentation is also used in the pharmaceutical and biotechnology industries to produce antibiotics, insulin, and other chemicals.
Yeast is a type of fungus and is typically found in a solid form, often as dry granules or in a wet paste. When activated in a liquid, such as dough, yeast ferments sugars and produces carbon dioxide gas, which causes dough to rise. So while yeast itself is solid, its activity can produce gas as a byproduct.
The gas that bubbles in the dough to make it rise is carbon dioxide. This gas is produced during fermentation by yeast or chemical leavening agents. The carbon dioxide forms bubbles in the dough, causing it to expand and rise.
Beer yeast can be used to make bread by activating it in warm water with sugar, then mixing it with flour and other ingredients to create dough. The yeast ferments the sugars in the dough, producing carbon dioxide gas that causes the dough to rise and create a light, fluffy texture in the bread when baked.
