1.	Study the graph given below and analyse the reasons for accumulation of lactic acid in blood after strenuous exercise.Athlete (Strenous excerise)Graph showing effects of vigorus excerise on the concentration of lactic acid in blood
Answer» 1. This graph shows the relation between time accumulation of lactic acid in the muscles. 2. At the beginning, the amount of lactic acid in the blood is very less. 3. Gradually it is increased by vigorous exercise. 4. Within 15 minutes it goes to maximum level which causes muscle pain. 5. Then the lactic acid is removed from muscles in an hour. 6. Muscles produce energy by anaerobic respiration. C₆ H₁₂ O₆ → lactic acid + CO₂ + energy 7. In the vigorous exercise, muscle work rapidly and produce more lactic acid. 8. That’s why lactic acid concentration is increased in muscle after strenuous exercise.
