This graph represents the blood lactic acid levels on an athlete running a 400 meter race: Respiration in athletics The blood of an athlete was tested before, during and after a 400m race: 12 Blood lactic 10 acid concentration g (mmol/litre) A B 30 C E 60 time in seconds

8. Use the graph to explain what metabolic processes are occurring over the 60-second race. 9. What metabolic process is more prevalent at point A? 10. Which metabolic process is more prevalent at point B? 11. Point D is towards the end of the race. Normally, lactic acid levels will drop over time. How do you explain the spike in lactic acid production at the end of the race?
