Observing Normal Catalase Reaction
Part A Overview
The purpose of Part A of this lab was to odserve the catalase reaction and find if catalase is reusable and if so how. Here in this part of the lab is what would be considered the control piece. This is where the standard comparison is developed to use throughtout the lab.
Reaction
When both the beef liver and hydrogen peroxide are added together in a test tube they release oxygen gas and leave a liquid composed of water. The reaction took 53.2 seconds. Which was measured as a 4 for the reaction rate. Added together they give off heat which is called an exergronic reaction. Which caused the test tube to be warm.

Is Catalase Reusable?
The liquid both the beef liver and hydrogen peroxide make is composed of enzymes. The prediction made was that the liver would react, but not as much as if you were to put more peroxide in the enzyme liquid. When this was tested the reaction rate was 0. Trying again, but adding more peroxide to the liver remaining in the first test tube. The reaction rate was 5. Catalase is reusable because the enzymes in the liver were able to help break down the hydrogen peroxide. Whereas, when the new liver was added to the enzyme liquid there was no reaction, but when more peroxide was added the reaction was the same as the very first reaction.
