Yeast, which is added to bread, makes it expand.
The yeast eats the sugars in the dough and produces carbon dioxide which forms little bubbles. The foamy dough takes up more room (expands).
Some breads (soda breads) use a chemical reaction to generate the carbon dioxide from baking powder.

∙ 9y agoDough with yeast increases in size (rises) because the yeast is a living organism. When combined with moisture and warmth, the yeast eats and digests the sugars in the bread dough, then produces gas. The gas expands as it warms, pushing against the dough and causing it to rise.

∙ 8y agoYeast is a living thing and basically it eats sugars and then produces gas which makes things like bread dough rise.

∙ 14y agoAs yeast grows it gives off gas; which causes bubbles to develop inside the dough and makes it rise. Yeast needs sugar or honey to feed its growth.

How does yeast work in the making of bread?
Yeast is an small animal that eats food like sugar (candy bars,oreo etc) then it farts out a special type of gas. Put yeast in dough eat the sugar in it the releases the gas and makes the dough or bread grow and expand. And we can eat it. Yeast works better in the heat so0 then the bread will expand faster. but not too fast. that why we bake the yeast and dough and at a certain temperature so it does expand to slow or fast.
What roles does yeast play in bread-making?
Yeast causes bread to rise. EDIT: Yeast reacts with sugar to make carbon dioxide gas. this creates bubbles in the bread mixture, causing the dough to rise. When you cut into a loaf - all those little 'holes' in the bread are the spaces left by the carbon dioxide bubbles !
What does yeast do in bread dough?
Baking yeast makes food rise and gives it a fluffy taste and feel to your food.
Is yeast what makes bread rise?
Yeast respires, producing carbon dioxide that makes the bread rise
Why bread dough rises?
The yeast cells in bread dough ferment sugars and produce gas (carbon dioxide). This makes the dough rise.
Why the bread expond?
Breads and quick breads expand because of air. In yeast breads the yeast eats the sugar and makes carbon dioxide that puts air into the bread. In quick breads a chemical reaction similar to vinegar and baking soda makes air that expands the bread. Bread that has been expended is softer to eat.
Is yeast found in flat bread?
NO, Yeast is what makes bread rise so therefor it cannot have yeast.
What does bread use for food?
bread uses yeast to grow. Yeast makes the bread nice and fluffy. :)
How does yeast effect bread dough?
yeast is a microscopic organism that makes bread rise
How is yeast used in baking?
Yeast makes the bread rise.
