4. ETC is made up of a series of protein complexes. Is the (circle one) FIRST or the LAST of the protein complexes in the ETC more electronegative (remember that more electronegative means more attraction for electrons)? Explain your answer!
5. What is the role of oxygen at the end of the ETC? What molecule is formed when oxygen does this job?
6. What specifically, does the energy released by the “falling” electrons do to H+ ions? Is this an active or passive process?
7. After the electrons have moved all the way down the ETC, where is the energy that was originally in glucose?
9. When hydrogen ions flow across the membrane through the molecular turbine what molecule is produced?______ What is the name of the molecular turbine? __________________ Is this movement of H+ ions a (circle one) active / passive process? Explain your answer!
Homework Answers
According to the HomeworkLib policy, I am only answering the first question of this post.
4. Electron transport chain consists of 4 different complexes within which electrons are transferred sequentially from one to the next. The last of the protein complex is more electronegative as compared to the initial ones because eventually the electrons has to reach the last complex.So, To accomodate the electron transfer sequentially , the last protein complex retains the more electron attracting power and thus is more electronegative.

Cellular respiration: The Electron Transport Chain The breakdown of glucose ends during the Krebs cydle; however, it is important to note that the energy previously contained in glucose is mostly stored in NADH and FADHz. In the last step of celular respiration, the high-energy electrons within NADH and FADH2 are passed within a set of proteins found in the inner membrane of the mitochondrion, collectively known as the electron transport chain. The electrons provide the energy to create ATP, which...

Q13 Cyanide is a deadly poison that attaches to cytochrome c oxidase, the last protein in the electron transport chain before the terminal electron acceptor. Based on your knowledge of the electron transport chain, which statement below best describes the action of cyanide on the body? A. Cyanide does not allow the Krebs cycle to be completed by blocking acetyl CoA from entering this cycle. This action shuts down the entire process of cellular metabolism. B. Cyanide does not allow...
