Abstract:

The objective of this lab was to determine the effects of certain variables on enzymatic activity and to get a quantitative feel for the effectiveness of a certain enzyme, in this case peroxidase obtained from potatoes. In order to do this, we conducted experiments in which the effects of boiling and inhibitors were examined by comparing normal enzymes to those affected by the factors being tested. Using a spectrophotometer, we analyzed the absorbance levels of the enzymes at various time intervals to determine how the enzymatic activity changed over time, as the enzyme’s catalytic effects began to be observable. Based on our results, we concluded that inhibitors and boiling both effectively disrupt enzymatic activity, reducing the normally linear reaction to nearly nonexistent.


Introduction:

Enzymes are proteins that act as biological catalysts. Because they speed up metabolic processes that would otherwise take too long to occur, they are fundamental to an...
