Peroxidase enzyme lab

peroxidase enzyme lab Since enzymes are necessary for catalyzing reactions in all living organisms, it's important for us to know how they work, and what can keep them from functioning properly.

The peroxidase reaction is as follows: 2 h2o2 + peroxidase --- 2 h2o + o2 + peroxidase water and oxygen are much less toxic than h2o2, and thus don't damage the interior of the cell experimental setup we extracted catalase from turnips, and investigated the effects of four factors on the speed of the enzymatic reaction.

1 binding of the substrate to the enzyme’s active site may result in the straining of one or more chemical bonds in the substrate, thus increasing the probability of bond(s) breaking (catalase and peroxidase destabilize the oxygen-oxygen and oxygen-hydrogen bonds in h 2 o 2, thus facilitating its decomposition) 2. The ph optimum of hrp is in the range of 60 to 65 activity at 75 is 84% of the maximum the enzyme is most stable in the ph range of 50 to 90 5 applications horseradish peroxidase is widely used as a label for immunoglobulins in many different immunochemistry applications including elisa, immunoblotting and.
