Paper Abstract

When cells are irradiated with visible and near-infrared wavelengths a variety of stimulatory effects are observed in their metabolism. To explain the observed light effects, researchers try to identify the chromophores that are involved in the processes. However, the mechanism of light absorption by a chromophore does not explain many of the experimental observations and therefore the primary mechanism for cellular light responses remains unproven. In addition to the ability of photons to produce electronic excitation in chromophores, light induces an alternating electric field in a medium that is able to interact with polar structures and produce dipole transitions. The effect of the light induced electric field in enzymatic molecules is analyzed in the present article, and it will be described how enzymatic activity is enhanced by this mechanism.
