The process of anearobic respiration of yeast in sugar solution is known as

The process of anaerobic respiration of yeast in a sugar solution is known as fermentation. During fermentation, yeast breaks down glucose in the absence of oxygen to produce energy in the form of ATP, as well as alcohol (ethanol) and carbon dioxide. This process is widely used in the food and beverage industry to produce beer, wine, and bread, among other products. The yeast consumes the sugars in the solution and converts them into alcohol and carbon dioxide through the process of fermentation. Therefore, the correct answer is fermentation.
