Webb23 okt. 2024 · A controversial alternative to the lock-and-key model suggests our sense of smell arises not just from the shape of molecules, but also from the manner in which those molecules vibrate. All molecules constantly jiggle with distinct tempos, based on their structure. Could our noses somehow detect differences in those vibrational frequencies? WebbThe Lock-and-key Hypothesis is a model of how Enzymes catalyse Substrate reactions. It states that the shape of the Active Sites of Enzymes are exactly Complementary to the shape of the Substrate.
