What ingredient makles bread rise?

Here's how it works:

* Yeast is a living organism that feeds on sugar and produces carbon dioxide gas and alcohol as byproducts.

* When you add yeast to bread dough, it consumes the sugars in the flour and starts to ferment, releasing carbon dioxide gas.

* This gas gets trapped in the gluten network formed by the protein in the flour.

* As the gas bubbles expand, the dough rises.

Other factors that contribute to bread rising:

* Temperature: Yeast works best in a warm environment.

* Moisture: Yeast needs moisture to thrive.

* Flour type: Different flours contain different amounts of gluten, which affects the rise.
