A study was made of photoinhibition of spinach chloroplast reactions. The kinetics and spectral characteristics of the photoinhibition over a range between 230 and 700 mμ have been examined. The ...

Ultraviolet light inhibits the photoreduction of 2,6-dichlorophenolindophenol or nicotinamide adenine dinucleotide phosphate with water as the electron donor (evolution of oxygen) but not the ...

The algae Chlamydomonas reinhardtii, shown here in a transmission electron micrograph, has been found to contain a light-activated system that can remove interrupting sequences from protein. [Mary ...

THIS communication describes an investigation of that portion of the photosynthetic mechanism that functions in the Hill reaction. Experiments consisted of irradiating samples of lyophilized ...
