What Role Do Quantum Effects Play in Enzyme Catalysis?
In enzyme catalysis, quantum effects such as tunneling and non-classical behavior are crucial. Enzymes often operate at conditions (e.g., room temperature, neutral pH) where classical over-the-barrier activation is unlikely. Proton and electron tunneling in enzymes can lead to highly specific and efficient catalytic processes. For instance, in oxidative phosphorylation, electron tunneling through enzyme complexes is essential for ATP synthesis.
