Which of the following statements is not true concerning the Entner-Doudoroff pathway?

E. coli can perform aerobic respiration, anaerobic respiration, and fermentation depending on environmental conditions. a.  Under which environmental conditions (ie., oxygen required; oxygen must not be present; oxygen presence doesn’t matter) would it perform each process? b.  What it the final/terminal electron acceptor for each process? c.  How is ATP produced (eg., photophosphorylation) in each process? (9 points, total) EXAMPLE:  glycolysis – oxygen presence doesn’t matter, NAD+ = electron acceptor, ATP is produced by substrate-level phosphorylation.
