Comparing photosynthetic and respiratory electron transport one notices key similarities as well as key differences. In which of the following ways is the two electron transport chains similar? 1. In both, electrons flow from a more negative to a more positive redox potential. 2. They both contain supermolecular complexes that hold redox-active cofactors. 3. They both can be uncoupled from ATP generation by the addition of chemical uncouplers. 4. The final product of both electron transport chains is an energy rich metabolite. A. 1, 2 and 3 B. 1 and 3 C. 2 and 4 D. 4 only E. All of 1, 2, 3 and 4 are correct.
