Yeast dough will rise more slowly if kept at a lower temperature. Chilling the dough in a refrigerator will cause slow, overnight rising. One can also use less yeast in proportion to the flour in the recipe.
Place it in a cooler enviroment.
To allow the dough to rise so you get a lighter, less dense end product.
To show that yeast was responsible for making the dough rise, you can conduct an experiment where you prepare two batches of dough- one with yeast and one without. Allow both doughs to rise, and observe that the dough with yeast rises significantly more due to the yeast's fermentation process producing gases that make the dough expand.
The yeast cells in bread dough ferment sugars and produce gas (carbon dioxide). This makes the dough rise.
Yeast dough is used to make all types of bread and pizza crusts. It is also used for rolls, including bagels, and snacks, including pretzels.
One reason yeast dies is that all the sugars in the dough have been consumed. When this happens, the dough goes "sour."
Circles of sweetened yeast dough are shapes of unbaked dough. Sweetened yeast dough can be baked as bread, rolls, or danish.
The main purpose is to make the bread more tender, but it also adds flavor and helps it to brown when baking.
Dough rises faster on a hot day because higher temperatures speed up the activity of the yeast, causing it to ferment and produce carbon dioxide more rapidly. The warmth also helps to relax the gluten in the dough, making it easier for the gas bubbles to expand and lift the dough.
-- carbon dioxide -- alcohol, if not attended to -- spores to make more yeast, if properly cared for
Yeast is a living organism that is mixed into dough. In the dough it finds a warm place with moisture and food (sugar) that it needs to grow and reproduce. Unlike us, animals that need oxygen to live, yeast can make do in both oxygen and non-oxygen environments. When it is working in a non-oxygen environment, like dough, it creates carbon dioxide (a gas). Being surrounded by dough, the gas has no place to go and accumulates into bubbles. The bread becomes essentially a dough froth and takes up more room than the solid dough had taken up. This is called rising.
Be careful here. I guess you could use more yeast, BUT it will make it taste slightly more 'yeasty'! If you want your bread to have that 'home-madey' taste, then it's probably best to stick to the recipe. Hope this helps :)
