The term yeast refers to a group of a hundred or so single celled organisms collectively known as Saccharomyces, which are a type of fungi. When you mix flour and yeast and dampen it, various things start to happen. In addition to the wheats own enzymes, which begin to convert sugar into starch, the yeast cellsproduce several enzymes of their own, which convert the various sugars in flour into forms the yeast can absorb.
This is how yeast feeds. Most enzymes inside the yeast cell convert these sugars into carbon dioxide and alcohol, which are excreted. The carbon dioxide forms into bubbles in the dough and cause it to rise. This is fermentation (from the Latin fermomeaning 'to boil') This enzyme activity helps to make the tough gluten in the flour more digestible. Not surprisingly, bread that ferments for longer is better for you.
After feeding heartily and passing gas accordingly, the yeast's cells turn to reproduction, so it splits in two. From then on 2 becomes 4, 4 becomes 8 etc etc... meanwhile some of the excreted alcohol becomes acetic acid, which makes the dough slightly more acidic. Yeast likes that, and the activity increases because of it. All this noticeably raises the temperature of the dough.
Conclusion: Yeast makes bread rise, and gives it the air bubbles inside.
What else can I help you with?
How does the reaction between bread and alcohol occur, and what effects does it have on the overall composition and flavor profile of the bread?
When bread and alcohol react, the alcohol helps to break down proteins and starches in the bread, leading to a softer texture and enhanced flavor. The alcohol also contributes to the fermentation process, which can create a more complex and aromatic flavor profile in the bread.
