Role of cyanide You are now convinced that you know the cause of death for these victims and quickly report it back to the police as this is a very dangerous situation. The poison was traced back to key strength tylenol where the study had opened the capsules and replaced acetaminophen a case killer with cyanide. On further investigation, it was shown that the tissues had major mitochondrial damage. Are they substrates or products? In fact, it was developed as a suicide pill called L- pill during World War II so that British and American spies could avoid being captured alive. Given what you know about cyanide poisoning, do you think that giving a person oxygen would be an effective treatment? Role of cyanide 20 minutes This last section of the case reveals that these patients have been poisoned with cyanide.
Were the levels higher or lower than normal? Since the Chicago Tylenol murders, drug companies have drastically changed how medicines are packaged. Given what you know about ATP and cellular respiration, explain why cyanide is so fast acting. Subcellular metabolite analysis Detailed analysis of the damaged cells showed that ATP levels in the mitochondria were very low. Is this a correct sentence “I would like my speaking to be improved. Why is the mitochondrion important? The Mystery of the Seven Deaths:
Are there any abnormalities in the levels of these metabolites in the victims? Even though the victims died of chicagl, their level of oxygen in their blood was approximately mm Hg.
It seems like a simple question, everyone knows you need to breathe to live. During this discussion, metabolites along with their functions in cellular respiration should be written on the board as a review for students.
While his family gathered to mourn their loss, his brother and sister became ill and later died. Recall that the mitochondrion is sometimes called the “powerhouse” of the cell. Given the data in the autopsy, were there any reports that seemed inconsistent with the immediate cause of death?
They suspected that someone had tampered with the medication. Cellular respiration case study answer key. Oxygen then binds with proteins to create water.
Cellular respiration case study answer key – service writer
The first was a year-old girl. Classroom management The case was developed for a class size of While poison is the main suspect in the case, what are other ways a person could die of hypoxia? That same day, paramedics found the second victim unconscious on his kitchen floor after what they thought was an apparent heart attack.
Autopsy report 15 minutes After class discussion of Part I, the instructor reports to the students that indeed all these cases do appear to be connected. Part I introduces the case and gets students to think epidemiologically about the information they receive.
JCST – May/June 2014
Students work in small groups of individuals to discuss answers to the case questions, followed by whole-class discussion. These questions can be written on the board. Cyanide is an extremely fast acting poison. Case teachers interested in this case may also be interested in another case in the collection entitled “A Headache to Die For” by Wayne Shew available at http: Why is cyanide such an effective poison? This case is based loosely on the real-life Chicago Tylenol murders in which seven people died from cyanide poisoning, which interrupts the function of the electron transport chain ETC.
For each metabolite listed in Table 1, describe its role in cellular respiration. Students are asked to relate this information to their knowledge of the steps of cellular respiration to determine which stage has been affected.
Part 2: Chicago Cyanide Murders- A Case Study in Cellular Respiration – Biology LibreTexts
Case Caxe with Quantitative Reasoning in Biology. Could this loss of function lead to the death of these individuals? They gave her an extra strength Tylenol and sent her back to bed. In the days that followed, three more unexplained deaths occurred in nearby Chicago suburbs.
While poison is the main suspect in the case, what are other ways a person could die of hypoxia? Cyanide irreversibly binds to cytochrome c oxidase CcOX of the electron transport chain and prevents the transfer of electrons to oxygen, the final electron acceptor.
Is this a correct sentence “I would like my speaking to be improved. On further investigation, it was shown that the tissues had major mitochondrial damage.
At the end of the electron transport chain, cytochrome C passes the electron to Complex IV and then to its final acceptor, oxygen.
Although this case was used in a small classroom, its format could easily be adapted for use in a larger class setting. How should public health officials and police respond to this tragedy? During the whole class discussion that follows, a list of questions is developed that the students cchicago should stkdy asked as part of an epidemiological study.
