What is the name of process where dough rises?

The process where dough rises is called fermentation. Fermentation is a metabolic process that produces chemical changes in organic substrates through the action of enzymes. In the case of dough, the enzymes present in yeast convert sugars into carbon dioxide and ethanol, which causes the dough to rise. The carbon dioxide gas forms bubbles in the dough, which expand and cause the dough to rise. The process of fermentation is also responsible for the characteristic flavor of bread.
