A Look at the Enzyme Catalase and How It Works in the Human Body
Hypothesis Enzymes such as Catalase are large protein molecules that are found in living cells. They are used to speed up specific reactions in the cells. They are all specific as each enzyme just performs one particular reaction. In their globular structure, one or more polypeptide chains twist and fold, bringing together...

An Experiment to Test the Effects of pH on Enzymes
Ryan Ohalleran 10/23/11 Bio Lab In the third exercise we worked in groups of fours to test the effects of pH on enzyme activity. The test subject was the liver cell, which was exposed to pH levels of two, eight, and fourteen, along with water and hydrogen peroxide. My hypothesis for this experiment was the lower th...
