Biophysics of photosynthesis

Abstract

A general review of the more physical aspects of photosynthesis is given. T h e subject is developed with reference to a time scale covering the various steps between photon capture and the appearance of the first stabilised chemical products. Details of the energy and electron transfer processes are considered and there is discussion of both the efficiency and mechanism for energy conversion.

Photosynthesis and the Application of Molecular Genetics

“…Photosynthesis and the application of molecular genetics 357 (Barber, 1978). The resulting products are the oxidant X (02 in the case of higher plants and algae) and a reduced hydrogen carrier, nicotinamide adenine dinucleotide (NADI) for photosynthetic bacteria and nicotinamide adenine dinucleotide phosphate (NADP ' ) for higher plants and algae.…”

Application of the Real-Space Renormalization Group to Dynamic Critical Phenomena

“…The "majority rule" choice with / = 1 leads to the "optimal" first-order statics. 8 Clearly the fixedpoint value / = 0 will lead to an inferior treatment for the statics.…”

“…As a result, one cannot make a reliable background subtraction to isolate the effects of superfluid fluctuations. 8 We thank Doug Paulson and John Wheatley for informing us of their preliminary results, and for permission to quote their results prior to publication. We are grateful to V. J. Emery for helpful discussions, and for pointing out an error in a preliminary version of this Letter.…”

Experimental Evidence on QCD

“…Planar events prefer small H 2 values. In Figure 26 H 2 is shown at 27 GeV (Barber et al 1980b) together with the predictions for the qq (with O"q = 0.325 GeVjc) and a QCD model (Ali et a1 1980). Compared to the qq model there is an excess of events with low H 2' QeD fits the data well.…”
