Webb10 maj 2024 · In the lock and key model, the shape of the active site matches the shape of its substrate molecules. This makes enzymes highly specific – each type of enzyme can catalyse only one type of reaction (or just a few types of reactions). Why are enzymes described as being like a lock and key? WebbJust as the right key can open a lock, similarly the right substrate with the same shape and size as that of the enzyme will react at the active site to yield the product.
