Taking reciprocals of both sides of this equation it becomes as follows: Se mer In biochemistry, the Lineweaver–Burk plot (or double reciprocal plot) is a graphical representation of the Lineweaver–Burk equation of enzyme kinetics, described by Hans Lineweaver and Dean Burk in 1934. The Lineweaver–Burk … Se mer $${\displaystyle [S]}$$: substrate concentration. The independent axis of a Lineweaver-Burk plot is the reciprocal of substrate concentration, $${\displaystyle {\frac {1}{[S]}}}$$ Se mer When used for determining the type of enzyme inhibition, the Lineweaver–Burk plot can distinguish competitive, pure non-competitive and uncompetitive inhibitors. The various modes of … Se mer • Michaelis–Menten kinetics • Eadie–Hofstee diagram • Hanes–Woolf plot Se mer The plot provides a very useful graphical method for analysis of the Michaelis–Menten equation, as it is difficult to determine precisely the Vmax of an enzyme-catalysed reaction: $${\displaystyle V={\frac {V_{\max }[S]}{K_{m}+[S]}}}$$ Se mer While the Lineweaver-Burk is useful for determining important variables in enzyme kinetics, it is prone to error. The y-axis of the plot takes the reciprocal of the rate of reaction, meaning … Se mer • NIH guide, enzyme assay development and analysis Se mer

A. To directly visualize K m & V max on the plot. B. To plot kinetic data as a hyperbolic curve instead of a line. C. To obtain a more accurate measure of the V 0. D. To remove terms that cannot be calculated in a typical enzyme kinetics ...
