Answer:
Two types of anaerobic respiration which occurs in cells are alcoholic fermentation and lactic acid fermentation.
Step-by-step explanation:
During alcoholic respiration, sugars such as glucose are converted into carbon dioxide and ethanol with the release of two molecules of ATP. This process does not occur in the human cells but is a common method of respiration for bacteria and other microorganisms. This method is essential for providing a wide number of products like wine, bread etc.
In lactic- acid fermentation, lactic acid is the final product. This process occurs in the muscles at the time of exercise when oxygen supply is less. However, this method is not as efficient as aerobic respiration.
