Thesis (Ph.D.)--The Ohio State University, 1988.

The aim of this research was to determine the free energy available for chemistry from photosystems I and II of green and blue-green algal photosynthesis. An integrating sphere was used to collect luminescence resulting from the back-reactions of the energy-storing systems of photosynthetic organisms. The intensity of luminescence from wild-type Scenedesmus obliquus was used to refine a previous determination of the free-energy change in photosystem II. With illumination at the light intensity required for carbon dioxide fixation by photosynthesis to be equal to carbon dioxide loss by respiration, named the compensation point (0.3 W/m$\sp2$ of 564 nm light), and free-energy generated by photosystem II was found to be 0.99 electron volts at 10 msec after cessation of actinic light.Subjects--Topical Terms:

520 $a The aim of this research was to determine the free energy available for chemistry from photosystems I and II of green and blue-green algal photosynthesis. An integrating sphere was used to collect luminescence resulting from the back-reactions of the energy-storing systems of photosynthetic organisms. The intensity of luminescence from wild-type Scenedesmus obliquus was used to refine a previous determination of the free-energy change in photosystem II. With illumination at the light intensity required for carbon dioxide fixation by photosynthesis to be equal to carbon dioxide loss by respiration, named the compensation point (0.3 W/m$\sp2$ of 564 nm light), and free-energy generated by photosystem II was found to be 0.99 electron volts at 10 msec after cessation of actinic light.
520 $a In the same manner, the weak luminescence from mutant #11 of Scenedesmus, dificient in plastoquinone A, was used to place a limit of the free-energy generated by photosystem I. It was found that the intensity of luminescence from the mutant samples places an upper limit of 0.73 electron volts on the free-energy change of photosystem I.
520 $a Luminescence from the cyanobacterium Anacystis nidulans in normal and calcium-depleted media was used in an effort to determine the free-energy generated by photosystems I and II of prokaryotes. The free-energy generated by photosystem II of cyanobacteria at the compensation point was found to be 0.88 electron volts. Neither the intensity nor the action spectra from luminescence of the calcium-depleted media showed photosystem I emission characteristics. Therefore, the cyanobacterium Aphanothece halophitica treated in an anoxygenic sulphide environment was used to determine the free-energy change of photosystem I in cyanobacteria, which was found to be 0.79 electron volts.
520 $a The combined energetics for PS-I and PS-II for both eukaryotes and prokaryotes added to the same figure, an average of 1.7 electron volts. This total for PS-I and PS-II provides just enough energy for the stabilization and production of chemical compounds from photosynthesis.
