Metabolic Control of Carbon Dioxide Fixation;

Carbon Dioxide Fixation by Extracts of Streptococcus

sence of exogenously added glutamate and pyridoxal-5'-phosphate and produced radioactive aspartate in the presence of these components. Reduced nicotinamide adenine dinucleotide or reduced nicotinamide adenine dinucleotide phosphate could not be substituted for adenosine triphosphate (ATP); phosphoenolpyruvate even in the presence of nucleoside diphosphates could not replace pyruvate plus ATP; ...

Carbon Dioxide Fixation in Marine Invertebrates*

Carbon dioxide fixation has not been studied extensively in the invertebrate animal groups. In an early study Van Niel et al. (1) with Cl1 showed fixation of COZ into succinic acid in the protozoan Tetrahymena geleii. Hultin and Wessel (2) studied incorporation of C% into proteins of developing sea urchin eggs (Psammechinus miliaris) with attention on metabolic patterns of development rather th...

A Sustainable Approach for Carbon Dioxide Fixation

Carbon dioxide is a green house gas that exists in earth’s atmosphere. In recent decade’s due to increment of population and rapid industrialization, the amount of CO2 has increased significantly and has caused global warming and other problems. Different methods are used for reduction of CO2 concentration in air one method is storing CO2 gas below the ground, but this manner doesn’t provide a ...

Carbon Dioxide Fixation by Detached Cereal Caryopses1

Immature detached cereal caryopses from barley (Hordeum vulgare L. var distichum cv Midas) and wheat (Triticum aestivum L. cv Sicco) were shown to be capable of fixing externally supplied"'CO2 in the light or dark. Green cross cells and the testa contained the majority of the 14Clabeled material. Some "4C-labeled material was also found in the outer, or transparent, layer and in the endosperm/e...
