Biocatalysis can be defined as the use of natural substances to speed up (or catalyze) chemical reactions. The natural substances of which I speak can be one or more enzymes or cells. An enzyme is simply a protein catalyst, and enzymes have many important uses.
Every reaction in any living thing,is proceeds thanks to the presence of enzymes. Enzymes help you digest food, produce vital nutrients, move muscles, and do just about everything else you can think of. Enzymes are also used in your daily life daily to improve the performance of detergents (“protein gets out protein”), make beer and wine, process food, allow diagnostic laboratories.
