WebThe Michaelis-Menten modelfor enzyme kinetics presumes a simple 2-step reaction: Step 1: Binding – the substrate binds to the enzyme Step 2: Catalysis – the substrate is converted to product and released (Note that enzymes not matching this reaction scheme may still show similar kinetics.) WebFeedback inhibition is a normal biochemical process that makes use of noncompetitive inhibitors to control some enzymatic activity. In this process, the final product inhibits the enzyme that catalyzes the first step in a series of reactions. Feedback inhibition is used to regulate the synthesis of many amino acids.
