WebEnzymes let chemical reactions in the body happen millions of times faster than without the enzyme. Because enzymes are not part of the product, they can be reused again and again. How efficient! This is an example of an enzyme molecule (blue) and a substrate (yellow). The enzyme and substrate fit together like a lock and key to make the product. WebEnzymes are essential for many biological processes, including metabolism, DNA replication, and protein synthesis. They are also used in industry for a wide range of applications, such as food production and drug development. 1. Function Enzymes Enzymes are proteins that catalyze, or speed up, chemical reactions in living organisms.

WebEnzymes catalyze chemical reactions by lowering activation energy barriers and converting substrate molecules to products. Enzymes bind with chemical reactants called substrates.
