### Using Microsoft Excel to Plot and Analyze Kinetic Data

By creating a double-reciprocal **plot** (or **Lineweaver-Burk plot**) the values m max for K and V can be determined from a regression line through the values for 1/S vs. 1/v.

### Using Microsoft Excel to Plot and Analyze Kinetic Data

Three **plots** were ® produced from each assay, one representing the Michaelis-Menton equation and the other two representing linearized forms of that equation, specifically a double-reciprocal **plot** called a **Lineweaver-Burk plot** and an m max Eadie-Hofstee **plot**.
