9. In the electron transport chain picture above, how do electrons move from protein complex I to protein complex II? 1. I need you to remember that "Q" is ubiquinone which gets reduced at proteins l & I, and oxidized at protein III. "Reduced" means gains electrons, "oxidized" means loses electrons. 2. I need you to remember how "Q" moves from protein I to protein Do you remember? Don't overthink it, Preeda. As far as scientists know right now, the...

What is the function of cytochrome c in the electron
transport chain?
Question 3 of 4 To answer this question, you may reference the Metabolic Map. What is the function of cytochrome c in the electron transport chain? o It reduces two molecules of Q to QH2. It oxidizes NADH to NAD+. It oxidizes FADH2 to FAD. It transports two electrons from NADH or FADH to complex III. It transports an electron from complex III to complex IV.

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...

QUESTION 4 You are studying an electron transport chain from a newly identified life form that has four electron carriers, a, b, c, and d. They function in the following order: substrate → → → → → 02 Three compounds are identified which inhibit this newly discovered electron transport chain in the presence of substrate and oxygen, yielding the patterns of oxidation states shown below. O and R indicate fully oxidized and fully reduced, respectively. Inhibitor ROOO Z o substrate...

If you say "no", then identify the specific step of glycolysis (draw it) that requires NAD. (c) During aerobic respiration, NAD* is regenerated when NADH donates its H atom to the electron transport chain. Explain how NAD is regenerated during fermentation. (d)...
