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.

All produces ATP.

The three metabolic processes called Glycolysis, acetyl CoA formation and Kerb's cycle together forms 36 ATP. The end product of all the three process is same by means that they all produce ATP along with other products.

The process of alcoholic fermentation or Glycolysis yields 6 ATP directly , whereas 6 ATP is obtained during Acetyl CoA formation from 2 molecules of NADH, and Kerb's cycle yields 24 ATP  in which 18 is obtained from  6 molecules of NADH and 4 from 2 molecules of FADH2 which all together yields around 36 ATP.

can you me this person for the answer

a lot of people sadly don't know the best way to learn is cheating off of your friends or this amazing thing called google
