Regulation of Purine Biosynthesis. The PRPP amidotransferase enzyme exists as an active monomer and an inactive polymer (see Introduction to Metabolism Lecture). IMP, GMP and AMP all inactivate the enzyme causing a shift towards the polymerized inactive form. PRPP causes a shift towards the active monomeric form.
Metabolic poisons, such as hydrogen cyanide and cyanogen chloride, inhibit cellular respiration, whereby cells extract oxygen from the blood and transform the energy in sugar molecules into a useful form of energy for cells.All systems of the body are ultimately affected by these metabolic poisons.etabolic poisons, such as hydrogen cyanide and cyanogen chloride, inhibit cellular respiration, whereby cells extract oxygen from the blood and transform the energy in sugar molecules into a useful form of energy for cells.
