Finding vmax from lineweaver-burk plot
WebPopular answers (1) It is difficult to provide a precise answer without seeing the raw data as a direct plot of rate versus substrate concentration. Kinetic parameters should not be … WebNov 8, 2024 · The Lineweaver–Burk plot was widely used to determine important terms in enzyme kinetics, such as Km and Vmax, before the wide availability of powerful computers and non-linear regression software. The y-intercept of such a graph is equivalent to the inverse of Vmax; the x-intercept of the graph represents −1/Km.

WebThe Lineweaver-Burk plot derives from a transformation of the Michaelis-Menten equation, v = V a K m + a {\displaystyle v={\frac {Va}{K_{\mathrm {m} }+a}}} in which the rate v … WebJul 12, 2024 · The y-intercept of the Lineweaver- Burk plot is the reciprocal of maximum velocity. How do you find Vmax? So, knowing the initial rate, Vo, and the various concentration of the substrate, you can create a straight line. The line plot represents the slope of Km/Vmax and y-intercept of 1/Vmax.
WebPractice: To determine the V max from a Lineweaver-Burk plot you would: A Multiply the reciprocal of the x-axis intercept by -1. B Multiply the reciprocal of the y-axis intercept by -1. C Take the reciprocal of the x-axis intercept. D Take the … WebA typical curve of enzyme kinetics is a plot of a plot of velocity of reaction vs substrate concentration.

The substrate concentration that gives you a rate that is halfway to V_ {max} V max is called the K_m K m, and is a useful measure of how quickly reaction rate increases with substrate concentration.
WebApr 11, 2024 · Transformation to the Lineweaver-Burk form: 1 v i = K m V m a x ( 1 s) + 1 V m a x ( 1 + i K i) ( 4) In this case, the inhibitor increases the apparent value of 1 / V m a x but does not effect K m / V m a x In other words, it effects the apparent value of V m a x, but has no effect on the specificity constant ( V m a x / K m ).
Webwas found by multiplying the Vmax by the slope to get a value of 0.277uM. For the half inhibited reaction the Vmax was 0.0973umoles/min and the Km was 0.0654uM. For the inhibited reaction the Vmax and Km were 0.627umoles/min and 1.595uM. respectively. The Michaelis Menten plot gave slightly different values from the Lineweaver Burke plot. … screw number 8WebFeb 15, 2006 · On a Lineweaver-Burk plot the y-intercept, or value at which the line intersects the y axis, is the reciprocal of Vmax.
