EQUATION FOR ANAEROBIC RESPIRATION (YEAST):

EXPLANATION: Yeast is used in baking bread and is mixed into dough prior to baking While baking, Yeast rapidly uses up all Oxygen present in the dough via aerobic respiration As a result, anaerobic respiration will occur to produce Carbon Dioxide, which forms bubbles that make the dough rise, and Ethanol, which evaporates into the atmosphere

EQUATION FOR ANAEROBIC RESPIRATION (YEAST):

EXPLANATION: Yeast can be used to produce Ethanol via fermentation Yeast is cultured in a liquid containing sugar and other Nutrients, except for Oxygen to ensure anaerobic respiration occurs to produce Carbon Dioxide, which bubbles into the atmosphere, and Ethanol, which gives Alcoholic content to drinks Beer, wine, and other Alcoholic drinks are brewed using this method
