Having now learned how to conduct basic cell culture, you are ready to complete your first experiments.  Below is a portion of the respiration pathway in O.Extremus in which electrons are transferred from NADH to O2; the energy of this reaction is coupled to the pumping of H+, and ultimately ATP production. O.Extremus displays abnormally high activity levels of an enzyme called ATPase.  This results in increased hydrolysis of ATP to ADP and later AMP. What effect would this have on the overall metabolic rate in these cells? Explain your reasoning.
