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 ...

This transformation enables the enzyme to better bind with its substrate (light pink puzzle piece). In contrast, an inhibitor molecule (pink circle) can prevent the interaction of an enzyme with ...

However, it is safe to say that no enzyme is perfect in the sense of catalyzing only a single reaction with a single substrate. For enzymes such as P450s and glutathione S-transferases that are ...

A continued increase in pH results in a sharp decrease in activity as the enzyme’s active site changes shape. It is now denatured. As the substrate concentration increases so does the rate of ...
