Imagine that you isolate two different strains of bacteria. Give two different possible pairings of electron donors and electron acceptors that you might find used by these two bacteria. glucose Electron donor: Electron Acceptor: CH 4 CO 2 Electron donor: Electron Acceptor: O 2 Any combinations are correct as long as the donor has higher potential energy than the acceptor. 3 pts
