Shapes of molecules lock and key model

WebbLock and Key Theory: The specific action of an enzyme with a single substrate can be explained using a Lock and Key analogy first postulated in 1894 by Emil Fischer. In this analogy, the lock is the enzyme and the key is the substrate. Only the correctly sized key (substrate) fits into the key hole (active site) of the lock (enzyme). WebbEnzymes are usually proteins, though some ribonucleic acid (RNA) molecules act as enzymes too. ... along with their positions in 3D space, give the active site a very specific …
