Photosynthesis, Melvin Calvin research

Calvin cycle, reductive pentose phosphate cycle, photosyuthetlc carbon reduction cycle a series of 13 enzyme-catalysed reactions, occurring in the chloro-plast stroma in plants or the cytoplasm in photosyn-thetic bacteria, which are organized into a cycle, the purpose of which is to convert CO2 into carbohydrate using the reduced pyridine nucleotide (NADPH in plants, NADH in photosynthetic bacteria) and ATP generated in the Ught phase of photosynthesis (see Photosynthesis). The cycle was di vered by Melvin Calvin, research that earned him the Nobel Prize for... 

Research Associate and Assistant Director, Bio-Organic Group, Radiation Laboratory, University of California, Berkeley. Research on the Path of Carbon in Photosynthesis with Melvin Calvin (Nobel Laureate, 1961). 

The chemistry of petroleum will be described here by Melvin Calvin, Professor of Chemistry and member of the Radiation Laboratory at the University of California in Berkeley and one of the world s outstanding organic chemists. Dr. Calvin is Director of the Bio-organic Chemistry Group at the Radiation Laboratory and is noted for his productive research in the chemical processes of photosynthesis. 

THE PATH OF CARBON IN PHOTOSYNTHESIS Our knowledge of the path of carbon in photosynthesis comes mainly from a series of brilliant researches initiated in 1946 by Melvin Calvin and his associates at the Lawrence Radiation Laboratory of the University of Cahfornia. These workers made use of the radioactive isotope of carbon, C, from which they prepared radioactive carbon dioxide ( COj) and then fed this to unicellular algae Chlorella pyrenoidosa and Scenedesmus obliquus) and green leaves.
