during which process is water produced?\no alcohol fermentation\no acetyl coa formation\no electron…

Brief Explanations:

In the electron - transport chain, oxygen acts as the final electron acceptor. Hydrogen ions combine with oxygen to form water. In alcohol fermentation, ethanol and carbon dioxide are produced. In acetyl - CoA formation, no water is produced. In the citric acid cycle, carbon dioxide is produced but water is not a direct product of the cycle reactions themselves.

Answer:

electron transport chain
