Why does yeast cause bread to rise?



  1. 0 Votes

    Yeast eats the sugars in bread when activated with hot water.  Through the digestion process, the yeast that grows produces carbon dioxide bubbles that cause the bread to rise.  When baked, the cells digest even faster, causing the bread to rise.  When the yeast dies, it causes the bread to deflate a little.  This is towards the end of the cooking process, and that is what keeps the bread from rising too much.
