Answer 2

In Alcohol Fermentation, the levels of atmospheric O₂ is below 1% and the amount of CO₂  released is relatively high

Explanation:

• The correct answer for this question is option C ( Alcohol fermentation is occurring).
• In anaerobic respiration, oxygen is absent. Alcohol fermentation usually occurs in an anaerobic condition to produce alcohol in the absence of oxygen and Co₂  is released.
• Alcoholic fermentation is a biological process that is carried out by microorganisms such as yeast and bacteria. In anaerobic conditions, these microorganisms convert organic food material into alcohol  and carbon dioxide as a byproduct.
• Alcoholic fermentation starts with glycolysis (the breakdown of sugar molecules), which produces two molecules of pyruvate.  
• Under anaerobic conditions, these two pyruvate molecules are first converted to acetaldehyde and then produce alcohol.
