Each enzyme molecule has a special place called the active site where another molecule, called the substrate, fits. The substrate goes through a chemical reaction and changes into a new molecule ...

The diagram shows how this works ... breaks the weak hydrogen bonds holding the enzyme’s unique active site shape. Enzyme–substrate complexes can no longer form as the substrates no longer ...

Enzymes are proteins that can change shape and therefore become active or inactive ... enables the enzyme to better bind with its substrate (light pink puzzle piece). In contrast, an inhibitor ...
