WebProgress curve for an enzyme reaction. The slope in the initial rate period is the initial rate of reaction v. The Michaelis–Menten equation describes how this slope varies with the concentration of substrate. Enzyme assays are laboratory procedures that measure the rate of enzyme reactions.
WebEnzyme progress curves. In most cases, an enzyme converts one chemical (the substrate) into another (the product). A graph of product concentration vs. time follows three phases marked on the graph below. 1. At very early time points (usually less than a second), the rate of product accumulation increases over time. Special techniques, not ... dodge ram towing truckWebFeb 5, 2024 · Yet progress curves are what most investigators record and analyze to determine initial rates v 0 and to calculate V M, K M and inhibition constants, as described above.
