NettetCreate a Lineweaver-Burk plot. Before nonlinear regression was available, investigators had to transform curved data into straight lines, so they could analyze with linear regression. One way to do this is with a Lineweaver-Burk plot, which plots the reciprocal of substrate concentration vs. the reciprocal of enzyme velocity. Nettetproblems 1.

NettetSubstrate-Velocity Curves and Lineweaver-Burk Plots 1 In this example, we’ll make a combination graph commonly used to characterize enzyme activity—a curve of initial velocity vs. substrate concentration, sometimes referred to as a Michaelis-Menten plot, with an inset Lineweaver-Burk plot. This article includes the following techniques:
Nettet5. mar. 2024 · For a Lineweaver-Burk, the manipulation is using the reciprocal of the values of both the velocity and the substrate concentration. The inverted values are then plotted on a graph as 1 / V vs. 1 / [ S ]. Because of these inversions, Lineweaver-Burk plots are commonly referred to as ‘double-reciprocal’ plots. ir sensor with raspberry piNettetLesson 3: Enzyme kinetics. Enzyme kinetics questions.
