Question

what do alcohol fermentation, acetyl coa formation, and the krebs cycle have in common?
all produce water.
all produce carbon dioxide.
all produce atp.
all produce alcohol.

Explanation:

Alcohol fermentation produces carbon - dioxide and alcohol. Acetyl CoA formation from pyruvate releases carbon dioxide. The Krebs cycle also releases carbon dioxide as a by - product. Water is not produced in alcohol fermentation. ATP is not produced in all steps of acetyl CoA formation in the same sense as in the Krebs cycle and not in alcohol fermentation in the same context. Alcohol is only produced in alcohol fermentation.

Answer:

All produce carbon dioxide.
