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. The citric acid cycle is part of aerobic respiration and produces ATP, \(CO_2\), and \(NADH\). The electron transport chain is also part of aerobic respiration and is mainly involved in ATP production through oxidative phosphorylation. Alcohol fermentation is a type of anaerobic respiration where pyruvate is converted into ethanol (\(C_2H_5OH\)) and \(CO_2\).

Answer:

alcohol fermentation
