Ferritin-Based Photo-Oxidation Of Biomass For Nanoparticle Synthesis, Bioremediation, And Hydrogen Evolution, Oscar Petrucci Dec 2013

Ferritin-Based Photo-Oxidation Of Biomass For Nanoparticle Synthesis, Bioremediation, And Hydrogen Evolution, Oscar Petrucci

Theses and Dissertations

The cell is the basic unit of all living organisms. It is an amazing machine capable of self-replicating, growing, and synthesizing and shuttling thousands of compounds. To perform all of these activities the cell needs energy. The original source of energy for all living beings is the Sun. The energy of the sun is collected by the autotrophs (mostly plants) through photosynthesis and stored in the chemical bonds of carbohydrates and lipids through carboxylic acid intermediates; animals use these compounds to obtain the energy for their cells. Most of the energy extracted by the cell comes from the citric acid …


The Photoreduction Of Indigo Carmine Flavin Mononucleotide And Diphosphopyridine Nucleotide, By Illuminated Chloroplasts, M. Odell Hobbs Apr 1958

The Photoreduction Of Indigo Carmine Flavin Mononucleotide And Diphosphopyridine Nucleotide, By Illuminated Chloroplasts, M. Odell Hobbs

Theses and Dissertations

An investigation was made of the photoreduction of indigo carmine dye and flavin mononucleotide (FMN) by an illuminated sugar beet leaf homogenate in the presence of 2,6-dichlorophenolindophenol dye (DPIP) and ascorbic acid. DPIP and ascorbate were absolutely required for the reaction. Reconstitution experiments indicated a requirement for a heat-labile factor present in the supernatant fluid following centrifugation of the leaf homogenate. This factor activated the photoreduction of indigo carmine more than 20 times. The photoreduction of FMN was activated 2 times by this factor. Studies on the stoichiometry of indigo carmine photoreduction revealed that one mole of ascorbate was photooxidized …
