Question

In bread making why does the dough rise when yeast is added to it?

Answer 1

Yeast lives on sugar. In dough yeast decomposes sugars into Carbon Dioxide and Alcohol. The Carbon Dioxide comes out and makes the dough rise.

Answer 2

Cakes and Breads are made by the help of yeast. The yeast reproduces very fast at suitable temperature and produces carbon- dioxide by the help of Fermentation of sugar.

As more and more gas is produced the dough rises in volume which makes breads and cakes porous and spongy.
