I've recently finished an experiment with hydrogen peroxide and enzymes.  I 
would just like a more in-depth reasoning of the reactions.  When I performed 
the first part of the experiment, I added H2O2 to a piece of liver, thus the 
catalse and H2O2 reacted quickly (breaking down) and O2 gas was formed.  For 
the second part I re-used the liver, and added more H2O2 and the same effect 
occurred. However, I do not understand how the liver can produce more catalase 
since it was already broken down during the first reaction. Is there a limit to 
the number of re-uses?
