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 does the gas from the yeast in bread do?
The gas released by yeast, CO2, creates bubbles, as the bubbles expand in the dough, the bread rises. As the bread bakes, the bubbles set and give the bread its light, airiness.
How does a yeast makes a bread to expand?
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.
