Question

1. Which molecule/complex in the electron transport chain would likely transfer electrons to SO4? Which molecule/complex in the electron transport chain would likely transfer electrons to Fe(OH)a? 2. 3. How might substituting the terminal electron acceptors SO4 or Fe(OH)s for oxygen affect the build up of H'ions one side of a membrane (as shown in figure 2)? 4. Considering your answer to the question above, how is ATP production affected?

Explanation / Answer

NADH coenzyme Q reductase transfers electrons to SO4.

Ubiquinone which transfers electrons to Fe(OH)3.
