Outline the lock and key mechanism of enzyme-controlled reactions

Enzymes are proteins that catalyse specific biological reactions in the body. These proteins have a specific 3D structure known as a teritary structure, with a specialised domain known as an 'active site' that is complementary to and specific for the substrate of the reaction they catalyse. This substrate binds the active site, like a key into a lock, allowing the reaction to proceed.
