Synthesize the biochemical transformations involved in converting glucose to ethanol and lactate during fermentation.

• A. Glucose is converted to lactate, which is then oxidized to ethanol.
• B. Glucose is converted to pyruvate, which is oxidized to acetaldehyde and then reduced to lactate.
• C. Glucose is converted directly to ethanol without intermediate steps.
• D. Glucose is converted to pyruvate, which is then decarboxylated to acetaldehyde and reduced to ethanol, or directly reduced to lactate.
