Web7 de may. de 2024 · V = V max S K M + S Taking the inverse of both sides to linearise the equation, 1 V = 1 V max + K M V max S Taking y = 1 / V and x = 1 / S in y = A + B x leads by linear regression to A = 0.4767, B = 4.4754 (not including units). Therefore, V max = 1 A = 2.10 m M s − 1 K M = B V max = 9.39 m M WebMeasuring KM and Vmax Run a series of reactions with constant [Etot], varying [S], and measure Vo. Graph Vo vs. [S]. Estimate Vmax from asymptote. Calculate Vmax/2 read KM from graph.
WebThis question does not appear to be about biology within the scope defined in the help center. Closed 4 years ago. In dealing with the question above I know that if we plot 1/v against 1/ [isocitrate] we can get V-max = 1/intercept and Km = slope/intercept. However when I express the two rows of values in micromoles I get intercept = 3359, and ... Web19 de abr. de 2024 · v = d [P]/dt = Vmax ( [S]/Km+ [S]) In the above equation, Vmax is the maximum rate achieved by the system that occurs at the saturated substrate concentration for a given enzyme concentration. Km is the Michaelis constant. If it is numerically equal to the substrate concentration, then the reaction rate is half of the value of Vmax.
