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 ...

Enzymes are highly specific to their substrates. They bind these substrates at complementary areas on their surfaces, providing a snug fit that many scientists compare to a lock and key.

Motivated by this, the fledgling bioengineer and his team created a new material that retains the key structural features of ...

This causes the formation of more enzyme-substrate complexes, leading to an increase in enzyme activity. This means the active site loses its important shape and can no longer form enzyme ...

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 ...
