What happens during anaerobic cellular respiration?

Answer:

During anaerobic cellular respiration, fermentation occurs in the absence of oxygen. In lactic acid fermentation, cells convert pyruvic acid into lactic acid and NADH is recycled back into NAD. In alcoholic fermentation, pyruvic acid is converted into carbon dioxide and ethyl alcohol. No additional ATP is produced during these fermentation processes beyond what was created during glycolysis.

Describe the impact cellular respiration has on other organisms and the environment.

Answer:

Cellular respiration provides organisms with usable energy and returns carbon dioxide and water to the environment, contributing to the carbon and water cycles. Anaerobic respiration by microorganisms also helps produce bread, cheese, and alcohol.
