WebbKm is theMichaelis-Menten constant, expressed in the same units as X. It describes the interaction of substrate and enzyme in the absence of inhibitor. If the data don't fit the model well, consider instead fitting to a noncompetitiveor uncompetitivemodel. Or fit to the more general equation for mixed-model inhibition. WebbDecomposition of soil organic matter (SOM) is mediated by microbial extracellular hydrolytic enzymes (EHEs). Thus, given the large amount of carbon (C) stored
