Enzymes are biological molecules ... In the induced-fit model, the active site and substrate don't fit perfectly together; instead, they both alter their shape to connect.

Thus, induced fit ensures that the biological function of the enzyme, catalysis, is not enabled until after a proper substrate is bound. Figure 2: The classic enzymological view of induced fit.

Enzymes are able to bind to their substrate because they have an active site. An induced fit occurs where the active site of the enzyme is changed slightly to better fit the substrate after the ...
