The process by which yeast produces the carbon dioxide responsible for bread rising is A. cellular respiration. More specifically, yeast undergoes fermentation, a type of anaerobic cellular respiration, where sugars are converted into alcohol and carbon dioxide. The carbon dioxide gas gets trapped in the dough, causing it to rise.
