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.
Background. The enzyme Catalase. Enzymes are proteins that help a certain chemical process take place. Chemical reactions require a certain amount of energy to take place.In the presence of the enzyme, the amount of energy required for the chemical process to take place is reduced.This happens because the enzymes bond with certain substrates to produce the end products.The reduction in the energy level helps to make the process happen faster.n the presence of the enzyme, the amount of energy required for the chemical process to take place is reduced.
