You are testing the effects of different molecules on respiration using isolated liver cells that are growing on glucose. For each of the compounds listed below, indicate whether the compound will increase or decrease respiration (measured by monitoring oxygen consumption), and provide reasoning for your answer in two sentences at most. Consider only the early time after the compound begins to exert its effects. a. An inhibitor of the FoF1 ATPase b. A proton channel that enables protons to cross the inner mitochondrial membrane by facilitated diffusion c. An inhibitor of NADH dehydrogenase (complex I of the electron transport chain)
