WebEthanol-from-biomass fermentation is an example of product inhibition, while high fermentable carbohydrate concentrations also can become inhibitive. Aiba and Shoda developed a mathematical model for the anaerobic fermentation, where nine constants are required to describe the model [13]. WebInhibitors are molecules which interfere with the substrate binding to the active site of an enzyme, slowing down or stopping the reaction. These may be reversible or non …

No matter how much substrate is added in this case, the reaction with the inhibitor can't catch up. There is more going on here than just competition for the binding site. In this case, the inhibitor is directly interfering with the product-forming steps of the reaction. island county wetland identification guide

WebReversible Inhibition by Reaction Products. Competitive inhibition can occur in freely reversible reactions owing to accumulation of products. Even in reactions that are not readily reversible, a product can function as an inhibitor when an irreversible step precedes the dissociation of the products from the enzyme. ... An example is salicylate ... WebOne class of examples occurs where one or more products of a pathway inhibit enzymes at the start of the pathway. This is known as product inhibition and is a form of negative feedback. A classic example of this is in glycolysis where ATP acts as an allosteric (non-competitive) inhibitor of phosphofructokinase.
