A fully functioning enzyme molecule is fold into a complex three-dimensional shape and this structure determines the specific type of molecules it interacts with during a reaction. Each functioning enzyme molecule has a particular structure to bind with a high degree of specificity to one or a few molecules and to carry out its function. Therefore, cellular function is directly associated to its structures.

This shape determines the specific type of molecule it interacts with

during a reaction. Enzymes are composed of a linear chain of amino acids that fold during the translation process to give rise to a three-dimensional tertiary structure of the enzyme, capable of presenting activity.
