Question

During lactic acid fermentation,

• A. $O_2$ is used, $C{O}_2$ is not liberated.
• B. $O_2$ is not used, $C{O}_2$ is liberated.
• C. $O_2$ is used, $C{O}_2$ is liberated.
• D. Neither $O_2$ is used, nor $C{O}_2$ is liberated.

Answer 1

The correct option is D Neither $O_2$ is used, nor $C{O}_2$ is liberated.

Lactic acid fermentation is anaerobic respiration that takes place in the muscles during vigorous exercise or jogging. In this process, due to insufficient supply of oxygen, lactic acid is produced from glucose which causes muscular cramps. The end product is lactic acid, there is no formation of Oxygen.

So, the correct answer is Nither O${}_2$, nor CO${}_2$ is liberated'
