Question

Lactic acid deposition leads to

• A. Tetany
• B. Muscle fatigue
• C. Muscle strain
• D. Convulsions

Answer 1

The correct option is B Muscle fatigue

• Generally, the glucose undergoes metabolism in the presence of oxygen to form ATP(adenosine triphosphate) which is essential for the muscle contraction but during vigorous exercise, the body cannot meet the oxygen demand and the glucose undergoes metabolism in the absence of oxygen which results in the formation and accumulation of lactic acid.
  
• Feeling of fatigue after vigorous exercise for some time is due to the accumulation of lactic acid in muscles.
• Hence lactic acid deposition leads to muscle fatigue.
• So, the correct answer is 'Muscle fatigue'.
