Question

In anaerobic respiration, yeasts can produce alcohol from pyruvate. Imagine a situation in which we control oxygen intake and initiate anaerobic respiration in our body, can we produce alcohol in our body?

• A. Yes we can produce alcohol in our body
• B. No, it's not possible, because lactate dehydrogenase is the enzyme which act on pyruvate in muscles
• C. None of these
• D. Alcohol consumption leads to acute diseases

Answer 1

The correct option is B

No, it's not possible, because lactate dehydrogenase is the enzyme which act on pyruvate in muscles

In anaerobic environment, some cells can use glycolysis and fermentation to keep producing ATP. Lactic acid fermentation happens in our muscle cells when we are exercising, while alcoholic fermentation is used in yeast cells and leads to production of beer, bread, and wine. So human body is incapable of producing alcohol during anaerobic respiration.
