1. Explain the importance of metabolic diversity to microbes and how the diversity allows different microbial species to colonize such a wide variety of habitats.



2.  E.coli is an example of a facultative anaerobe.  Explain what this means with respect to oxygen use, and explain the two metabolic pathways that E.coli can use in both presence and absence of oxygen.  Be sure to include the important substrates and byproducts of each of these pathways.
