Abstract

Photosynthesis is a chemical process through which light energy is used to convert inorganic material (water and carbon dioxide) into organic molecules. Anaerobic photosynthesis, also known as anoxygenic photosynthesis, is the process by which certain bacteria use light energy to create organic compounds but do not adequately involve oxygen. In this experiment we are trying to influence photosynthesis (light and dark reactions: PS-I and PS-II by electron rich gadolinium/iodine complexes like Eovist and Isovue. We also performed X-ray and NIR reflection spectroscopy (NIRS) to measure Gd difusivity and PS-I/II infrared response. The results for X-ray (45kvp and 5 Mas ) showed the movement and diffusion of Gadolinium (Gd) and is shown on our Fig2. Also, NIR spectrograph experiment Fig.5 showed some peaks that might correspond to photosynthesis induced by NIR light. The findings of the research will show if the pathway of photosynthesis can be accelerated or decelerated by injecting Gd or Iodine complex that also happened to be ideal for the x-ray.
