Yeast can metabolize sugar in two ways, aerobically, with the aid of oxygen, or anaerobically, without oxygen. In both cases, carbon dioxide, CO 2, is produced. The rate that this gas is produced is referred to as the rate of respiration. Objectives

WebAug 8, 2024 · In short, in the fermentation process, the yeast eats sugar and they produce carbon dioxide (CO 2) gas and alcohol. The alcohol is a boon for winemakers and brewers, and the CO 2 comes in handy for bakers. CO 2 also produces the bubbles in beer. WebSep 4, 2024 · Alcoholic fermentation requires the electrons from NADH and results in the generation of NAD+. Yeast in bread dough also uses alcoholic fermentation for energy and produces carbon dioxide gas as a waste product. The carbon dioxide that is released causes bubbles in the dough and explains why the dough rises.
