Bee Sting,
Fall 2014

The Case: It’s a warm Fourth of July and you are walking across the park to your favorite picnic spot. You are allergic to and highly phobic about bee stings. While walking, you hear a buzzing sound to your right. You turn your head and see a large bee hovering over your right shoulder. You reach with your left hand to swat the bee, but just as you make contact, it stings you anyway. You notice that you are sweating and your skin turns red. You realize that your Epi-pen was left in the car, so you panic and begin sprinting back to the car to get it.’

The Assignment: Name and describe all of the anatomic structures and physiological actions involved with this incident including hearing and seeing the bee, turning your head and swatting at the bee. Where did the muscles get the energy for this action? What tissue types and skin layers did the stinger invade? Explain how your body responded to this event. This is an opportunity to review much of the information presented during this semester. It will give you an opportunity to integrate the multiple systems into a single 60 second physiological episode. This assignment could be seen as a very intense and major (perhaps overwhelming) undertaking, but the outline below should make it more palatable.

Administrative Instructions:
1. Form small groups of 2 to 6 students to complete this assignment. Each group is to do its own work: No information is to be shared between groups. Evidence of answer sharing will result in both groups receiving a zero. Do not discuss or share your answers with anyone outside of your group, including your lab instructor or tutor. 2. Do not divide the questions among group members. Every member of the group is to fully understand all the answers to this assignment so that you may double check each other and create the best answers possible. I may call on any member of a group to explain their answer to any question. 3. This assignment is to be typed and posted to the drop D2L drop-box by the due date (save the file in a WORD compatible form). One document posted per group. 4. Put all answers in your own words. DO NOT COPY from any source (including the textbook). Do not ‘paraphrase’ by re-arranging a few words. 5. Include the questions, question numbers and point values with your answer. 6. Give your references for each answer and provide a Works Cited page at the end (in APA or MLA style). Give Page numbers for textbook citations and complete URL for all web-based references. DOIs are acceptable as well.

Outline: Answer the following questions in order and you will have completed the assignment. Be sure to include the question with your answers and provide proper citations within each answer. 1. (6 pts) Describe the metabolic process providing your energy while you were walking (at an easy pace) before the bee stung you. Include which molecules are being consumed, the various intermediate molecules and which energy molecule is being regenerated.

Our bodies, even at rest, rely on aerobic metabolism to fuel our energy needs. As we begin to exercise, our energy needs increase and our bodies will begin to burn the molecules. Walking is a mild endurance exercise and primarily uses aerobic respiration of glucose. This is done in three phases: Glycolysis, Krebs Cycle and Electron Transport System. ATP is the energy molecule produced during this process.

Aerobic respiration is the process by which sugars (glucose) is transferred into adenosine triphosphate (ATP), usable energy. During Glycolysis, one 6-carbon glucose is transformed into two 3-carbon pyruvate molecules. This breakdown of glucose requires the use of 2 ATP to start the process and happens in the cytoplasm. This process creates four ATP molecules and two nicotinamide adenine dinucleotide...
