Quizplus · Accepted Answer

Under anaerobic conditions (when oxygen is not present), the electron transport chain in cells cannot function properly. Instead, pyruvate (the end product of glycolysis, which is the first step in cellular respiration) is converted into lactate as a way to regenerate NAD+ (a molecule needed for glycolysis to continue). This process is called lactic acid fermentation. Therefore, lactate is produced from pyruvate under anaerobic conditions.
