Explain the role of enzyme conformational dynamics in facilitating quantum effects, such as tunneling and coherence, during catalysis.

Enzyme conformational dynamics, which refer to the constant fluctuations and movements of the enzyme's structure, play a critical role in facilitating quantum effects like tunneling and coherence during catalysis. These dynamics can transiently bring reactants into closer proximity and optimal alignment for tunneling. For tunneling, the enzyme's conformational changes can reduce the distance and width of the potential energy barrier that the tunneling particle must traverse. These changes may occur through protein vibrations....
