Diagram lock and key model example.

In 1894 emil fischer suggested that both the enzyme and the substrate have specific complementary geometric shapes that fit exactly into one another. Select rectangle tool and block arc tool to create the basic lock shape as follows. For example if a qwerty input method is used with a qwertz keyboard some letters such as y and z will not produce the key press as labeled on the keys. It supposes that the substrate fits perfectly into the active site of the enzyme.
