WebMay 2, 2024 · K aplan-Meier curves are widely used in clinical and fundamental research, but there are some important pitfalls to keep in mind when making or interpreting them. In this short post, I’m going to give a basic overview of how data is represented on the … A language model and more — The long-awaited release of the latest Generative … WebSep 1, 2014 · Km is the Michaelis constant. It is the substrate concentration that gives rise to a reaction velocity that is 50% of Vmax. Km has the same units as the substrate … WebKm = Michaelis constant. Although Km values are more or less constants for particular enzyme-substrate systems, but these may vary slightly with pH, temperature, ionic strength and also with types and amount of coenzymes when required for the reaction. The values of Km are measured in terms of molarity. improv comedy west palm beach
