Answer 2

Answer:

1: reduction of acetyldehyde to ethanol

Explanation:

• NAD+ is generated during the glycolysis process when acetaldehyde is reduced to ethanol.
• Ethanol fermentation releases CO2 from pyuvate and reduces the two-carbon acetaldehyde molecule to ethanol, resulting in the regeneration of NAD+ from NADH.
• To convert pyruvate to lactate, electrons from NADH and a proton are needed.
