Publisher Summary The high level of diversity among photosynthetic bacteria, including
cyanobacteria, stands in contrast to the relative uniformity found among the chloroplasts of …

Photosynthesis is a biochemical process by which plants and certain bacteria capture
sunlight and convert it to chemical bond energy. The end result of this process is the …

The cyanobacteria and prochloroaceae are the only prokaryotic groups that share the use of
photosystems I and II and hence the ability to carry out oxygenic photosynthesis with all …

The origin of life on this planet, the “Mystery of Mysteries”(Darwin, 1859), remains a matter
for debate, but it seems likely that early organisms were chemoautotrophs, perhaps using …

The cyanobacteria, together with phototrophic green and purple bacteria and
prochlorophytes, share a basic prokaryotic cellular organization and together constitute the …

8. I Introduction This review is centred on the biochemical and biophysical aspects of
photosynthetic energy conversion in the cyanobacteria. The details of the photosynthetic …

Photosynthesis begins with the absorption of light in a set of" light harvesting" or" antenna"
pigment molecules, principally chlorophylls (1). The absorbed energy used for …

Photosynthesis, the conversion of sunlight into energy that is available to sustain cellular
metabolism, is accomplished by a diverse group of organisms. The present photosynthetic …

Comparative biochemical studies of photosynthetic organisms, pioneered by van Niel some
fifty years ago, are a particularly fruitful method of elucidating the current relationships and …
