Question

What do alcohol fermentation, acetyl CoA formation, and the Krebs cycle have in common?

A. All produce water.
B. All produce carbon dioxide.
C. All produce ATP.
D. All produce alcohol.

Answer 1

Ans. (B). All produce carbon dioxide.

During alcohol fermentation, sugar (such as glucose) molecules convert in ethanol and ATP molecules, while carbon dioxide is released as a byproduct.

During acetyl CoA synthesis, one molecule of pyruvate combines with co-enzyme A to make acetyl COA and carbon dioxide is released as a byproduct.

During Krebs cycle, a series of chemical reactions take place to release energy stored in acetyl-CoA through its oxidation into ATP and carbon dioxide is released as a byproduct.

Hence, the common thing between all these three processes is the release of carbon oxide.

Thus, the correct answer is option (B).

Answer 2

Base on my research about the said problem that ask on what does the alcohol fermentation, acetyl CoA formation, and Krebs Cycle have in common and base on that question, I would say that the answer is in letter B. All produce carbon dioxide. I hope you are satisfied with my answer and feel free to ask for more
