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.

c.) polymerase chain reaction

- "unlike the original dna fingerprinting method, dna profiling does not use restriction enzymes to cut the dna. instead it uses the polymerase chain reaction (pcr)? to produce many copies of specific str sequences. pcr is an automated procedure that generates lots of copies of a specific sequence of dna."
