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

Glucose is converted to lactate, which is then oxidized to ethanol.

Glucose is converted to pyruvate, which is oxidized to acetaldehyde and then reduced to lactate.

Glucose is converted directly to ethanol without intermediate steps.

Glucose is converted to pyruvate, which is then decarboxylated to acetaldehyde and reduced to ethanol, or directly reduced to lactate.
