In which of the following component of the body, does lactic acid fermentation takes place:
Correct answer: D. Muscles
- A. Brain
- B. Heart
- C. Liver
- D. Muscles
Explanation
Lactic acid fermentation occurs in the skeletal muscles. When oxygen is inadequate, pyruvate is converted to lactic acid by lactate dehydrogenase. It results in the accumulation of lactic acid and muscle fatigue. A.Lactic acid accumulates in muscles during anaerobic respiration causing muscle fatigue. B.Heart muscles donot fatigue and so lactic acid doesnot accumulate. C.Lactic acid doesnot accumulate in liver

About Bioenergetics
Cellular respiration explains how cells release energy from glucose through glycolysis, the link reaction, Krebs cycle and electron transport chain. It includes ATP production, substrate-level and oxidative phosphorylation, aerobic versus anaerobic respiration, and the roles of mitochondria, oxygen and fermentation in energy transfer.
