Respiratory processes in non-photosynthetic plastids

Frontiers in Plant Science, 2015
Chlororespiration is a respiratory process located in chloroplast thylakoids which consists in an electron transport chain from NAD(P)H to oxygen. This respiratory chain involves the NAD(P)H dehydrogenase complex, the plastoquinone pool and the plastid ...

Multistationary and oscillatory modes of free radicals generation by the mitochondrial respiratory chain revealed by a bifurcation analysis.

PLoS Computational Biology, 2012
The mitochondrial electron transport chain transforms energy satisfying cellular demand and generates reactive oxygen species (ROS) that act as metabolic signals or destructive factors.

Fluoride affects distribution of absorbed excitation energy more in favour of photosystem 1

Biologia Plantarum, 2010
The effects of fluoride on the photosynthetic electron transport chain have been studied in spinach thylakoid membranes. Inhibition in photosystem (PS) 2 electron transport rates and a subsequent increase in PS 1 electron transport rate indicated a ...

Improved efficiency of NiOx-based p-i-n perovskite solar cells by using PTEG-1 as electron transport layer

APL Materials, 2017
We present efficient p-i-n type perovskite solar cells using NiOx as the hole transport layer and a fulleropyrrolidine with a triethylene glycol monoethyl ether side chain (PTEG-1) as electron transport layer.

Comparsion of the Effects of Succinate and NADH on Postmortem Metmyoglobin Redcutase Activity and Beef Colour Stability

Journal of Integrative Agriculture, 2014
In two experiments, the effects of succinate and NADH (reduced nicotinamide adenine dinucleotide) on metmyoglobin reductase activity and electron transport chain-linked metmyoglobin reduction were investigated and compared. In experiment 1, metmyoglobin (

Investigating the Effect of Incorporating Dimethylaminopropyl Side Chains into a Naphthalenediimide‐Based Conjugated Polymer

Advanced Electronic Materials
Two approaches—fractional side‐chain truncation and complementary interactions—are employed in this study. In fractional side‐chain truncation, NDIDmap with the naphthalene diimide (NDI) group and the 3‐(dimethylamino)propyl (Dmap) chain is incorporated ...

Evidence for a hydrogenosomal-type anaerobic ATP generation pathway in Acanthamoeba castellanii.

PLoS ONE, 2013
Diverse, distantly-related eukaryotic lineages have adapted to low-oxygen environments, and possess mitochondrion-related organelles that have lost the capacity to generate adenosine triphosphate (ATP) through oxidative phosphorylation. A subset of these

Electron transport in xanthine oxidase. A model for other biological electron transport chains

Biophysical Journal, 1976
Part of the catalytic function of xanthine oxidase (XO) involves the transfer of two electrons from a substrate to a molybdenum ion on the enzyme followed by equilibration of these electrons among other electron resting sites on the enzyme. The electrons are removed from the enzyme at a flavin by oxygen to form hydrogen peroxide.
