Kinetics Parameters for Catalase Part 1: Vmax and Km

This video tutorial by Kevin Tolkoff explains how to use a Lineweaver-Burk plot to calculate the VMAX and KM of the enzyme catalase. The tutorial covers the advantages of using Lineweaver-Burk plots over Michaelis-Menten plots, and provides a step-by-step guide to finding VMAX and KM using the Y=MX+B equation. The video also discusses the significance of these kinetic parameters and prepares viewers for the next video, which will cover kcat and catalytic efficiency.
