(biochemistry)
An enzyme that catalyzes the conversion of phosphate and adenosine diphosphate into adenosine triphosphate during oxidative phosphorylation in mitochondria and bacteria or phosphorylation in chloroplasts.

What are the consequences of the "activity-driven ATP synthesis" in the synaptic mitochondria?
Thus, the oxygen consumption required for ATP synthesis ([OCR.sub.ATP]) in LPS-stimulated cells was lower than that in control cells whereas [H.sup.+]-leaking remained unchanged.
So, used in maintenance and repair of cells and tissues of the body, with calcium also provides structure and strength as part of teeth and bones, also used for nerve signaling, regulation of heart beat, also required for pH regulation and for many biochemical processes in the body such as ATP synthesis (Mason et al., 2011).
The ATP synthesis involves a series of electron transport reactions in the inner mitochondrial membrane, where oxygen is an essential component to facilitate the oxidation of substrates that ultimately allows ATP production (Mitchell 1966, Boyer 1997).
Mitochondrial complex 1-driven ATP synthesis assays (mtCIDAS) of vehicle- and CPC-treated LHON mutation (11,778) carrying osteosarcoma cybrid cells were performed as previously described with slight modification (Datta et al.

In this study, we submitted bovine epididymal spermatozoa to treatment with the oxidative phosphorylation uncoupler carbonyl cyanide 4-(trifluoromethoxy)phenylhydrazone (FCCP) to significantly reduce mitochondrial ATP synthesis and stimulated the glycolytic pathway by glucose addition.
However, excessive MPTP opening will lead to inner membrane potential collapse, respiratory chain uncoupling, and halt of mitochondrial ATP synthesis. Eventually mitochondria become swelling and rupture and ensue with cell death [4].
The rotational portion of these motors acts as a camshaft, inducing conformational changes that lead to ATP synthesis in the F1 motors three functional catalytic sites.
Multimodal neuroimaging provides a highly consistent picture of energy metabolism, validating [.sup.31]P MRS for measuring brain ATP synthesis. Proc.
Researchers found that poly-ADP-ribose (PAR), one of the main actors in chromatin de-compaction and DNA damage repair is the cornerstone for the nuclear ATP synthesis. Its building blocks of ADP-ribose are used by the nuclear enzyme NUDIX5 to generate ATP.
