3. At what point in experiment two do you think that your muscle cells converted from aerobic respiration to lactic acid fermentation?
4. -Why did your muscles start to get sore after a while? 
5. How would changing a variable (i.e. squeeze time, rest time or some other variable you chose) lead to different results? Explain. 
6. What would happen if you did not stop squeezing the tennis ball? What do you think would happen to your muscle cells and body as a whole? Could you survive off of lactic acidosis fermentation alone?
