Iridium spark plugs vs copper

This is because most allosteric enzymes contain multiple sub-units which can affect each other when the substrate binds to the enzyme. Inhibition can affect either K 0.5, which is the substrate concentration for half-saturation, Vmax or both. This results in a shift of the curve to the right, and in the case of reducing Vmax, shifts the curve down.
For enzyme assays it must be considered that enzymes reactions depend on more factors than pH, temperature and ionic strength. 2 Of great importance are the actual concentrations of all assay components. Further influences of compounds not directly involved in the reaction may occur, e.g. interactions of ions, especially metal ions, hydrophobic substances or detergents with the protein surface ...
Factors that can affect laboratory investigations In 2013 we published an article entitled "Best tests?" (Best Tests 18; Feb, 2013). In this article we challenged clinicians to consider whether they could improve the method and manner in which they request laboratory investigations.
