WebFigure 7.6.1 - The induced-fit model 7.6.3 Explain that enzymes lower the activation energy of the chemical reactions that they catalyse. Reactants of a chemical reaction need to gain energy before they can undergo the reaction. WebApr 26, 2014 · In the induced-fit model, the active site and substrate don't fit perfectly together; instead, they both alter their shape to connect. Whatever the case, the reactions that occur accelerate ...

WebSep 15, 2024 · The current theory, known as the induced-fit model, says that enzymes can undergo a change in conformation when they bind substrate molecules, and the active site has a shape complementary to that of the substrate only after the substrate is bound, as shown for hexokinase in Figure 18.6. 3. WebTRANSCRIPT 7.10: Induced-fit Model Most chemical reactions in cells require enzymes—biological catalysts that speed up the reaction without being used up or permanently changed. They work by reducing the activation energy needed for the reactants to be converted into the products. WebThe induced-fit theory explains a number of anomalous properties of enzymes. An example is “noncompetitive inhibition,” in which a compound inhibits the reaction of an enzyme but does not prevent the binding of the substrate. dhhs crescent city
