Oxygen is added to bread dough through the process of kneading. When dough is kneaded, the gluten in the flour is formed into a network that traps air bubbles. These air bubbles help the dough rise during fermentation, leading to a light and airy bread texture.
yes
It IS chemical, but it's not a heat reaction. It's respiration. Yeast is a living organism, which consumes sugar and excretes CO2 and alcohol. - - - - - chemical, because its reacting with heat & that always means chemical. it just includes a physical change..
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.
Yeast breaks down sugars in the bread dough through a process called fermentation. This breakdown releases carbon dioxide gas as a byproduct, which gets trapped in the dough, causing it to rise and become light and fluffy.
Baking bread causes the starches in the dough to break down, making it easier for our bodies to digest. The heat from baking also denatures the proteins in the dough, which can help improve digestibility. Additionally, baking eliminates any harmful bacteria that may be present in the unbaked dough, further aiding digestion.

A chemical change
It reacts with the sugars to make it rise.
Yeast is added to bread along with moisture and sugar, and the dough is kept in a moist, warm environment. During this rising time, the yeast consumes the sugar in the dough and release CO2 gas, which is trapped in the dough and causes the dough to rise. When the dough is baked, the yeast is killed, but the bubbles created by the gas remain.
Yeast added to bread dough produces a gas, and this causes the dough to rise, making the finished bread look like a sponge.
Yeast makes the dough rise. That is why your bread is fluffy instead of just being flat.
Bread is not "formed" by microorganisms. However, yeast is added to bread dough as leavening. The yeast, consisting of many billions of microorganism, consume and digest sugars in the dough which produces gas. The gas bubbles cause the bread dough to expand or "rise."
To allow the bread to rise. During the rising process, the yeast produces gases that form bubbles in the dough, making the dough lighter and "fluffier" than it would be otherwise.
The yeast feeds on carbohydrates in the dough and produces Carbon dioxide gas, this is what causes all the little bubbles that are present in bread and what causes it to "rise." It is left for a while in order for this process to happen and is usually allowed to double in size. Bread with no yeast in it is called "unleaven Bread."

Pot of flour + jug/bucket of water = dough (pick bread dough).
