Studies of factors involved in oxidative phosphorylation.

The oxidation of substrates of the citric acid cycle in mitochondria is coupled with the phosphorylation of ADP to ATP.I Considerable progress has been made in our understanding of the three electron transport reactions between DPNH and oxygen (DPNH -.cytochrome b -. cytochrome c -° 02), which are associated with the phosphorylation mechanism.2 In several laboratories3-7 actively phosphorylatin...

The mechanism of uncoupling of oxidative phosphorylation by 2,4-dinitrophenol.

2,4-Dinitrophenol fails to stimulate the breakdown of the soluble high energy intermediate of oxidative phosphorylation isolated from Alcaligenes faecalis extracts. Once the intermediate is broken down, by other reactions, the coupling enzyme is prevented from reassociation with the electron transport particles by 2,4-dinitrophenol. Phosphorylating particles washed with 2,4-dinitrophenol lose c...

Oxidative phosphorylation in fractionated bacterial systems. 18. Phosphorylation coupled to different segments of the respiratory chains of Mycobacterium phlei.

A number of bacterial systems have been described which will carry out oxidative phosphorylat,ion (1-12). In general these systems differ from intact mammalian mitochondrial systems in that the bacterial systems have lower P:O ratios and fail to exhibit respiratory control. Loss of sites of phosphorylation (13, 14) and nonphosphorylative electron transport bypass reactions (13, 15-18) has been ...

مروری بر نقش محافظتی ترکیبات پلی فنلی (رسوراترول، کوئرسیتین و کورکومین) بر عملکرد میتوکندری قلب

Mitochondria plays a major role in maintaining homeostasis of heart cells. Mitochondria produce ATP and is the main intracellular source of reactive oxygen species (ROS) which can cause oxidative damage. Free oxygen radicals and oxidative damage are associated with cardiovascular pathology. Antioxidant defense can play an essential role in preventing oxidative damage by controlling free oxygen ...
