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;

B. All produce carbon dioxide.

Explanation;

-Alcoholic fermentation is a process in which sugars such as glucose are converted into small amounts of energy in form of ATP, and producing ethanol and carbon dioxide.

-Acetyl CoA is produced through decarboxylation of pyruvate in the matrix of the mitochondria. This results to a molecule of Acetyl CoA and carbon dioxide.

-Kreb's cycle is the second phase of cellular respiration which involves the sequence of reactions by which most living cells generate energy.  The process takes place in the mitochondria, utilizing oxygen and producing carbon dioxide and water as waste products, and ADP is converted to energy-rich ATP.

-From these descriptions it is evident that the similarity among the following processes is that all produce carbon dioxide.
