What is the role of anaerobic respiration in yeast during the production of ethanol for biofuels?

In yeast, anaerobic respiration (fermentation) plays a crucial role in the production of ethanol for biofuels. During fermentation, yeast converts glucose into ethanol and carbon dioxide, allowing the production of ethanol, which is used as a renewable energy source in biofuels. This process also helps to preserve the yeast culture and enhance its growth in low-oxygen environments.
