Question

during which process is ethanol produced?
○ lactic acid fermentation
○ alcohol fermentation
○ citric acid cycle
○ electron transport chain

Explanation:

• Lactic acid fermentation produces lactic acid, not ethanol.
• Alcohol fermentation (also called ethanol fermentation) is a metabolic process where glucose is converted into ethanol and carbon dioxide, so this process produces ethanol.
• The citric acid cycle (Krebs cycle) is part of cellular respiration, producing ATP, NADH, etc., not ethanol.
• The electron transport chain is the final stage of cellular respiration, generating ATP via oxidative phosphorylation, not ethanol.

Answer:

B. alcohol fermentation
