Since competitive inhibitors do not change the Vmax but increase the Km, the double-reciprocal line will increase its slope and change its x-intercept but keeps the y-intercept unchanged. labor service schneck

Lineweaver-Burk_plot

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 inhibition can be compared to the uninhibited reaction. Competitive Inhibition Vmax is unaffected by competitive inhibitors. … 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 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 small errors in measurement are more noticeable.

NettetWhat is a Lineweaver-Burk plot competitive inhibition? A competitive inhibitor increases the slope of the line on the LineweaverBurk plot, and alters the intercept on the x-axis (since Km is increased), but leaves the intercept on the y- axis unchanged (since V max remains constant). Nettet11. apr. 2024 · I think it is possible to identify the type of inhibition from (initial) velocity vs substrate-concentration curves, but it is difficult.
