The enzyme that is responsible for the darkening of cut surfaces of fruits, vegetables and plants are called polyphenoloxidase. These enzymes, like all all other biological catalysts that cause us to exist, are often taken for granted. Without this enzyme, fruits, plants, and vegetables would-be left unprotected from different infections and diseases. There would be no response to the injuries, tissues in plants, fruits and vegetables might incur. Also, an absence polyphenoloxidase would leave humans without a skin pigment to tan. Thus, to understand this enzyme more in depth this paper will show the results of the research done on the effects of different concentrations of the enzyme, and the effects temperature will have on the rate of the reaction. In theory, the reaction rate should be proportional to enzyme concentration (“Factors Affecting Enzymes”); thus, the outcome of the experiment was successful. The results for the effects on temperature also appeared to be consistent with the hypothesis that reactions take place best in 35° C; temperatures close to normal body temperature….
