URGENT Biology lab help needed...EASY question!? - easy biology labs- respiration

We had a bio-laboratory, where yesterday I had tubes with a bucket in the liver at each, interspersed with sand and 20 ml of hydrogen peroxide. We have seen what happened in each tube. In the tube 1 in the liver was normal, but in the tube 2, the liver was crushed. In each tube with the same reactions, the two tubes. One of the issues to be addressed to:

How to compare results of the test tube 1 and 2? Is that what she has been the enzyme in liver cells would normally be expected?

I thought that the tube does not react with chopped liver as much as with the whole liver. I do not know how to explain why though. To do something to change the form of the enzyme and not be able to do their job or something. HELP!
