Enzymes typically are large molecules. They bind their “substrates” at only one location: The “Active Site”. This is hexokinase binding a glucose molecule.

The enzyme changes shape as it binds the substrate. The fit is like “hand in glove”. Numerous weak bonds must be made simultaneously. So, the active site surface and the substrate surface must be complementary. (Fit together.) Often there is a distinction between left and right. The enzyme that binds D- glucose cannot bind L-glucose.
