Yeast are among the few living organisms that do not need oxygen in order to produce energy. This oxygen-independent state is called anaerobic (pronounced a-na-ROE-bik; without oxygen). During such anaerobic conditions, yeast convert carbohydratesâstarches and sugarsâto alcohol and carbon dioxide gas. This process is known as fermentation. The fermentation process of yeast is caused by enzymes, catalysts in chemical reactions similar to the digestive enzymes in the human body.
Fermentation produces ATP in much smaller. amounts than cellular respiration and it also produces other organic. compounds. The type of organic compounds that are the end products of. fermentation depend on the type of cell that is fermenting, the enzymes. that cell has available to catalyze the reactions, and the type of substance. being fermented. Yeast produces ATP, ethanol, and carbon dioxide in the. presence of carbohydrates.
