Linear weaver burk plot
NettetThe Lineweaver-Burk (LB) equation is a linear transformation of the Michaels-Menten equation and it is used to provide a more accurate determination of the kinetic parameters, Vas, Kuand Vwku. The relationship between the LB equation and the equation for a line is shown below. 1.K1.1 vo Vmax [s])* Vmax y = mx + b Part 1: Double Reciprocal Plots … NettetAfter plotting 1/V0 against 1/ [S] following the Lineweaver-Burk plot, I got the equation y=9423.2x - 50545. So following the equation 1/V0 = (Km/Vmax) (1/ [S]) + 1/Vmax, both Vmax and Km would have a negative value since the y-intercept is negative. If I’m not wrong, both values are supposed to be positive.

I suggest you use non … tara restaurant walthamtara richards aglNettetAt low substrate concentrations (i.e., large values of 1/ s ), the Lineweaver–Burk plot appears linear as the reaction exhibits approximate first-order kinetics. By inference then, the apparent linearity of Lineweaver–Burk or similar plots cannot be considered sufficient evidence of the absence of mass transfer restrictions. tara rhodes buffalo nyNettetThe Lineweaver Burk plot is a graphical representation of enzyme kinetics. The x-axis is the reciprocal of the substrate concentration, or 1 / [S], and the y-axis is the reciprocal of the reaction velocity, or 1 / V. In this way, the Lineweaver Burk plot is often also called a double reciprocal plot. tara rheubottom baton rougeNettetUse the relationships revealed by a Lineweaver-Burk plot and the table of enzyme performance to calculate the Vmax and KM of the enzyme with no inhibitor, with inhibitor A, and with inhibitor B. 1/V Slope KM/v max Intercept-1/KM Intercept 1/Vmax 1/IS) SI (HM (umol/min); with (umol/min); with (Hmol/min); with no inhibitor inhibitor A inhibitor B 3 … tara rheubottom baton rouge la
