Hormone control of plasma membrane oxidation-reduction reactions

Control of Cell Growth by Plasma Membrane NADH Oxidation

Most cells that have been tested have two trans plasma membrane electron transport systems for the oxidation of cytosolic NADH. The first is an oxidase which transfers electrons from NADH to oxygen through dehydrogenases to coenzyme Q and a terminal reduced coenzyme Q oxidase. The second system for trans membrane electrontransport from NADH is a protein complex called porin or Voltage Dependent...

Oxidation-reduction reactions of metal ions.

Several metal or metalloid ions exist in multiple oxidation states and can undergo electron transfer reactions that are important in biological and environmental systems. There are endogenous metal ions such as iron, copper, and cobalt that participate in oxidation-reduction reactions with species of oxygen like molecular dioxygen, superoxide, and hydrogen peroxide. These reactions may be modul...

Photochemical Reduction and Oxidation Reactions on Barium Titanate Surfaces

The influence of the ferroelectric domain structure of BaTiO3 on the photochemical reactions that occur on its surface has been examined using atomic force microscopy. Both the photochemical reduction of aqueous silver cations and the oxidation of steric acid thin films were studied. During reduction, silver selectively deposits on the surface in patterns determined by the ferroelectric domain ...

Single Platinum Atoms Electrocatalysts: Oxygen Reduction and Hydrogen Oxidation Reactions

Atomically dispersed catalyst consisting of Pt atoms arranged in a c(2 × 2) array on RuO2(110) substrate was prepared. A large interatomic distance of Pt atoms in a c(2 × 2) phase precludes the reactants to interact with more than one Pt atoms. A strong bond of Pt atoms with RuO2 prevents agglomeration of Pt atoms to form 2D-islands or 3D-clusters. Activities of single Pt atom catalyst for the ...
