Hypothetically, if electron pools existed in sufficient numbers for enzymes to use in metabolic reactions,
A. a higher diversity of cytochromes would likely be observed.
B. cytochromes would be unnecessary for cells and quinones would be more important.
C. Q-cycle reactions would no longer be necessary for electron transport, but the proton motive force would otherwise be unchanged.
D. most metabolic pathways for both anabolism and catabolism would have to be rewritten.
