Summary Introduction

To write: The volcanic eruptions of the Permian period and Pangaea formation.

Introduction: There are five mass extinctions that are documented so far in the fossil record over a period of 500 million years ago. The fossil record of mass extinction is mainly from the hard-bodied animals in shallow seas. During this event, about 50% of marine species have become extinct.

The Permian and Cretaceous mass extinction received an important attention, since the mass extinction happened between the Palaeozoic and Mesozoic periods. During this event, about 96% of marine animal species drastically altered their life in the ocean.

Awnser these Discussion Questions Answer these discussion questions and submit them as part of your lab report. Part A: The Effect of Temperature on Enzyme Activity Graph the volume of oxygen produced against the temperature of the solution. How is the oxygen production in 30 seconds related to the rate of the reaction? At what temperature is the rate of reaction the highest? Lowest? Explain. Why might the enzyme activity decrease at very high temperatures? Why might a high fever be dangerous to humans? What is the optimal temperature for enzymes in the human body? Part B: The Effect of pH on Enzyme Activity Graph the volume of oxygen produced against the pH of the solution. At what pH is the rate of reaction the highest? Lowest? Explain. Why does changing the pH affect the enzyme activity? Research the enzyme catalase. What is its function in the human body? What is the optimal pH for the following enzymes found in the human body? Explain. (catalase, lipase (in your stomach),…
