Summary Introduction

To determine: The change in the shape of the tube due to the contraction of the circular muscle layer of the intestine.

Introduction: The gastrointestinal tract consists of a series of multiple hollow organs. Thes organs include the mouth, esophagus, stomach, small and large intestine. The lining of these organs is made up of unstriated muscles.

Summary Introduction

To determine: The change in the shape of the tube due to the contraction of the longitundinal muscle layer of the intestine.

Introduction: the The inner lining of the gastrointestinal tract is made up of smooth muscles. These are non striated and involuntary muscles. These muscles contract and relax to support the movement of substances inside the hollow organs.

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),…
