Coenzyme [edit]. A coenzyme is a small, organic, non-protein molecules that carries chemical groups between enzymes. It is the cofactor for the enzyme and does not form a permanent part in the enzyme's structure. Sometimes, they are called cosubstrates and are considered substrates that are loosely bound to the enzyme. In metabolism, coenzymes play a role in group-transfer reactions, such as ATP and coenzyme A, and oxidation-reduction reactions, such as NAD+ and coenzyme Q10. Coenzymes are frequently consumed and recycled.
Denaturing of enzymes. The important part of an enzyme is called the active site. This is where specific molecules bind to the enzyme and the reaction occurs. Anything that changes the shape of the active site stops the enzyme from working.This is similar to a key that opens a door lock.he important part of an enzyme is called the active site.
