The metabolic pathway below is used for the production of the purine nucleotides adenosine monophosphate (AMP) and guanosine monophosphate (GMP) in eukaryotic cells. Assume each arrow represents a reaction catalyzed by a different enzyme. Using the principles of feedback inhibition, propose a regulatory scheme for this pathway that ensures an adequate supply of both AMP and GMP, and prevents the buildup of Intermediates A through G when supplies of both AMP and GMP are adequate.
