Let's pretend you were the found of the ETC (sending respect to Peter D. Mitchell - the real founder!). After concluding there are 4 electron accepting complexes involved, you try blocking each of them individually to find out unique characteristics about each of them. When you blocked complex lll, all ATP production stopped and the proton gradient dissipated. When you blocked complex l, the ATP production was only down regulated but it still took place. The same thing happened when you blocked complex ll. What could explain these findings?
Cyanide is known to cause extremely quick death. Its main action is on complex lV of the electron transport chain. It acts to inhibit the reduction of O2. Working backwards through the chain, indicated all the problems that make this toxin so lethal.
If QH2 donated its electrons to complex lll but then didn't move to its secondary site on complex lll, what would be the result? Select all that apply
