One drawback from the Eadie–Hofstee approach is that neither ordinate nor abscissa represent independent variables: both are dependent on reaction rate. Thus any experimental error will be present in both axes.

The abscissa refers to the (x) coordinate and the ordinate refers to the (y) coordinate of a standard two-dimensional graph.

Irreversible inhibitors, such as the organophosphorus and organomercury compounds, cyanide, carbon monoxide and hydrogen sulphide, combine with the enzyme to form a covalent bond.

#Unit 1. Molecules and their Interaction Relevant to Biology

The extent of irreversible inhibition of the enzyme is dependent upon the reaction rate constant (and hence time) for covalent bond formation and upon the amount of inhibitor present.

The irreversible inhibitors cannot be removed by simple physical techniques such as dialysis, is to reduce the amount of enzyme available for reaction.
