The Quantum Yield of Oxygen Production by Chloroplasts Suspended in Solutions Containing Ferric Oxalate
1. The quantum yield of oxygen liberation by spinach and Tradescantia chloroplasts suspended in solutions containing ferric oxalate and potassium ferricyanide varied from 0.013 to 0.080. 2. It was concluded that the nature of this oxygen liberation reaction is not fundamentally different from the formation of oxygen in normal photosynthesis, with respect to its light efficiency.
متن کاملFlash photolysis studies on nitric oxide-ferrihemoprotein complexes. Evidence for the photodissociation into the ferric state.
In order to study the kinetic behavior of ligand binding, flash photolysis is widely used with various hemoproteins [l-4]. The applicability of this method, however, seems to be limited to the ferrous ligated complexes, such as CO, O2 and NO complexes, since it has been believed that only those ferrous complexes are photodissociable. To extend this technique to the ferric state, we have examine...
متن کاملMechanism of Initiation of Polymerization by Ferric Acetylacetonate
Results on the autooxidative decomposition of the transition metal B-diketonates (1-3) suggested the possibility of these chelates acting as initiators for the radical polymerization of vinyl monomers. Research in this field soon revealed the importance of the central metal atom as well as the ligand structure (4-10). Of a series of metal acetylacetonate~-Mn(Acac)~, M n ( A ~ a c ) ~ , Fe( A ~ ...
متن کاملMechanism of inactivation of the flavoenzyme lactate oxidase by oxalate.
Lactate oxidase from Mycobacterium smegmatic is strongly inhibited by oxalate. The inhibition is reversible in the absence and irreversible in the presence of light. Oxalate is bound to the enzyme in a two-step process with an over-all Kd of 1.6 times 10--5 M. The first step is a fast second order reaction with k-1/k1 equals 8.3 times 10--3 M, leading to a Complex I. This complex is then revers...
متن کاملMechanism underlying the low prevalence of pediatric calcium oxalate urolithiasis.
PURPOSE Urinary macromolecules in children show stronger inhibition of Ca oxalate crystal growth, aggregation and adhesion than in adults. To investigate the mechanism of Ca oxalate urolithiasis we evaluated the differences in inhibitory activity against oxalate induced renal cell injury between adults and children. MATERIALS AND METHODS Urine samples were collected from healthy men and their...
