Ribose is the initial substrate for the synthesis of AMP and GMP (purine nucleotides and the precursors of ATP and GTP respectively). The following diagram is a simplified overview of this overall metabolic pathway. The numbers refer to enzymatically-catalyzed steps in the pathway. a) Which enzyme is most likely to […]

While studying the Michaelis – Menton kinetics of enzymes in the TCA cycle, the synthetic hydrocarbon malonate was shown to act as a competitive inhibitor of one of the enzymes. At first, the identity of the inhibited enzyme was unknown but further tests revealed that this inhibited TCA enzyme was […]
