Polymer Principles
... • It recognizes that these molecules are not rigid, they are flexible. As they combine, each mloecule induces the proper fit of the other one. An enzyme, for example, can conform to the shape of the substrate. As it does this it places a strain on the chemical bonds in the substrate. This can chemic ...
