As a forensic pathologist, you have just completed an autopsy of a poisoning victim. After a thorough examination, you conclude that the victim died of cyanide poisoning. You know that cyanide binds to the cytochrome oxidase complex, and therefore list the official cause of death as suffocation due to cyanide exposure. However, if you wanted to provide a more technical explanation as to the cause of death, which process was specifically inhibited directly by cyanide?
A. The reduction of NAD+ B. The oxidation of FADH2 C. All proton pumping into the intermembrane space D. The formation of water from oxygen E. ATP synthesis Clarify Question What is the key concept addressed by the question? What type of thinking is required? Gather Content What do you already know about cellular respiration and cytochrome oxidase? What other information is related to the question? Choose Answer Do you have all the information needed to determine which specific process is directly inhibited by cyanide? Reflect on Process Did your problem-solving process lead you to the correct answer? If not, where did the process break down or lead you astray? How can you revise your approach to produce a more desirable result?
