Spectral Photoresponse of Biological Systems

Abstract

The effects the spectrum of incident radiation can have on photobiological processes are studied experimentally and theoretically. The potential effective fluxes of visible light are calculated for energetic and regulatory processes. With these data at hand, we find a correlation between the spectral photoresponse and the energy characteristics of plant photoreceptor and photosynthesis systems. A qualitative model for a photosensitive organic system is formulated as a circuit diagram that includes semiconductor photocells. The thermodynamic and electrical parameters of the modeled system are described. We draw parallels between the functioning of phototransistors and photoreceptor complexes PHOT, CRY, Ph(660), and Ph(730). The control parameters of the energy-distribution process in a living system are estimated using mathematical modeling and an experimental model based on photocells.
