CHICAGO CYANIDE MURDERS CASE STUDY IN CELLULAR RESPIRATION

Any opinions, findings and conclusions, or recommendations expressed in this material are those of the author and do not necessarily reflect the views of the National Science Foundation. In your opinion, are the seven deaths connected. Sadly, the victim’s brother and fiancee also collapsed later that night while the family gathered to mourn his passing. Place an X over the protein that is inhibited by cyanide. At the end of the electron transport chain, cytochrome C passes the electron to Complex IV and then to its final acceptor, oxygen.

In your opinion, are the seven deaths connected? In your opinion, are these seven deaths connected? Even though the victims died of hypoxia, their level of oxygen in their blood was approximately mm Hg. Why or why not? The medical examiner concluded that each of the victims had died of hypoxia. Sadly, the victim’s brother and fiancee also collapsed later that night while the family gathered to mourn his passing.

The electron stops at the end of the chain and cannot be passed to oxygen.

Why Do We Need Oxygen? Several studies have demonstrated a link between warfarin use and Between September 29 and October 1,seven people in the Chicago area each contained 65 milligrams of cyanide — 10, times more poison than.

It is an interrupted case study, where students are given sequential portions of the case to analyze. That same day, paramedics found the second victim unconscious on his kitchen floor after what they thought was an apparent heart attack.

Inside the mitochondrion, there are several layers of membranes. At the end of the electron transport chain, Cytochrome C passes the electron to its final acceptor, oxygen.

In your opinion, are the seven studdy connected? If poison were suspected in the deaths, how would you proceed with the investigation? Levels of pyruvate and acetyl coenzyme A CoA were normal.

A Case Study in Cellular Respiration 7. Cyanide acts very quickly, often killing within minutes of ingestion and authorities were slow to identify the cause of the deaths. Part I introduces the case and gets students to think epidemiologically about the information they receive. At the end of the electron transport chain, cytochrome C passes the electron to Complex IV and then to its final acceptor, oxygen. Cellular respiration; hypoxia; blood oxygen; metabolic pathway; metabolite; pyruvate, acetyl coenzyme A; NADH; cytochrome c oxidase; respiratoon transport chain; adenosine triphosphate; ATP; product tampering; cyanide poisoning; Tylenol.

At 7 am the next morning, her daughter was found collapsed on the bathroom floor, and later pronounced dead. The proteins in the membrane pass electrons from one to the other, this is known as the electron transport chain. Are they substrates or products? The electron stops at the end of the chain and cannot be passed to oxygen.

Both had taken Tylenol to help them cope with their loss shortly before collapsing; neither survived. Given the data in the autopsy, were there any reports that seemed inconsistent with the immediate cause of death? The poison was tespiration back to extra strength tylenol where the murderer had opened the capsules and replaced acetaminophen a pain killer with cyanide.

The Mystery of the Seven Deaths

In September ofMary Kellerman gave her year-old daughter a Tylenol when she awoke during the night complaining of a cas throat. At 7 am the next morning, her daughter was found collapsed on the bathroom floor, and later pronounced dead. An expanded version of the teaching notes and the answer key may be found at the National Center for Case Study Teaching in Science at http: Investigators found that all of the victims had taken an extra strength Tylenol hours before their deaths.

Table of Antidotes Word Document, The poison was traced back to extra strength Tylenol where the murderer had opened the capsules and replaced acetaminophen the active ingredient in Tylenol with cyanide.

The case can be completed in approximately one minute period or spread out over two minute periods. While his family gathered to mourn their loss, his brother and sister became ill and later died.

Given what you now know about the action of cyanide on cellular respiration, explain why the patients died of lack of oxygen while their blood oxygen levels were normal. Cyanidee is your job to answer these questions before more deaths are reported. Why or why not? It could also be used in any course where students are learning a basic understanding of the cellular respiration pathways; however, it is not advanced enough for use in upper level courses without modification.
