Multiple Choice
Which is evidence for gluconeogenesis being a more ancient metabolic pathway than glycolysis?
A) The protein sequences for the gluconeogenesis enzymes are less conserved than those for glycolysis,indicating greater diversity developed by evolution.
B) Many archaebacterial enzymes for gluconeogenesis have the same catalytic triad as those in modern mammals.
C) Glycolysis in bacteria generally has fewer pathway steps,indicating that it has had less time to evolve.
D) Some bacterial species that diverged very early in prokaryotic evolution have gluconeogenesis,but not glycolysis.
