Summary Introduction

To review:

The reason that athletes often move to elevations higher than those, at which they will compete, several months before a competition.

Introduction:

Red Blood Cells (RBCs) play an important role in the body of an organism. They carry oxygen from lungs to different tissues. RBC is produced in red bone marrow and each has a lifespan of 120 days. The level of hemoglobin or number of RBCs determines the oxygen transport to the tissues. Hemoglobin is a globular protein, which contains two alpha chains, two beta chains and a non-protein pigment called heme. There are four heme units in one hemoglobin molecule and each heme unit can hold an iron, which binds to an oxygen molecule.

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),…

Explain why it was necessary to use boiling alcohol? What is the purpose of the iodine? Part Two What was the purpose of keeping the leaf in the dark and then covering it with a cardboard cut-out? What conclusions can you draw from this part of the lab? Part Three 7. In this experiment what was the purpose of adding the soda lime? 8. Why was a sealed bag placed around each plant? 9. What happened in the control plants? 10. What was the result on photosynthesis? Part Four 11. Why was a variegated leaf used in this experiment? !2. What conclusions can you draw about starch production in a variegated leaf?
