Then we measured the rate of reaction of three different concentrations of catalase.

Time (s)
 Catalase B
 Catalase C
 Catalase D

Trial 2

Trial 3

 352



Analysis:

We decided that the higher the concentration of catalase, the higher the rate of reaction. We believe this is because there are more enzymes to react with the substrate at the same time. Also we think this isn't applicable to the substrate concentration. We believe the data will be asymptotic if it is persued further because the enzyme substrate ratio will be an improper fraction, leaving no substrate behind to react to the enzymes.

 

Are Enzymes Alive?

We don't believe enzymes are alive because they originated from living things.

 

 

 

 

We mixed .5 ml of H2O2 with a 7.4 pH buffer and measured the gas given off by the reaction, over time.
