broken down into an intermediate and thereafter harmless substances water and oxygen. The goal of this lab is to measure the reaction rate of this process in different substances such as a liver‚ a vegetable‚ and breast tissue. By using variables such a pH and temperature we are able to how the rate of reaction is altered or improved. If it has improved‚ the optimum has been discovered and the enzyme will create a higher reaction rate. If above the optimal points‚ proteins will denature and the reaction

CHAPTER 1 INTRODUCTION 1.1 ENVIRONMENTAL POLLUTION BY TEXTILE WASTEWATER It is well known that the earth’s surface and the environment surrounding are the most crucial to human health. In recent years‚ the environmental crisis is a major problem all around the world and it had adversely affect the lives of millions of people and caused many death and health disorders. Nowadays‚ toxic organics in wastewater had become a major problem to the earth creatures. These toxic organic occurs

Conclusion “How can we test and treat the Acme wastewater?” We need to test the pH to see what the waters health is. We also need to see if there is any copper in the water‚ if there is‚ we need go go throught the procedure. If the water is turbid‚ we need to figure out a way to make it clear and clean. My hypothesis was partially correct and incorrect. It was correct because we did need to test the water to see if it was hazardous‚ and part of it did. We needed to fix that fast. It was partially

How is pH affecting catalase activity? Hypothesis The catalase activity is assumed to be the most active in pH7. The higher or lower concentration away from the optimum pH of catalase‚ the slower the rate of activity is. Data Collection & Processing I collected the results of pH4‚ pH7‚ pH10 and pH13 after 2 minutes‚ and I repeated the experiment 3 times. Below is a table to show the results‚ their averages and standard deviations: | 1st time (sec) | 2nd time (sec) | 3rd time (sec)
