Shapes of molecules lock and key model
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? Webb26 okt. 2024 · In a shape theory, the smell of an odorant is encoded in the shape of the odorant molecule, which in turn determines the receptors in which it fits. This is a lock …
