WebInduced Fit Model. After all, the induced fit model continues to maintain that enzyme substrates are not exactly fitted to the active sites of their respective enzymes before binding takes place (the opposite was the lock and key model, proposed by a man named Emil Fisher; this model was widely accepted for quite a while, but did not explain ... WebMar 21, 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 3. After catalysis, the enzyme resumes its original structure.
