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?
