In order to decompose water into hydrogen and oxygen without the net consumption of additional reactants, a steady stream of reacting materials must be maintained in consecutive reaction processes, to avoid reactant replenishment or additional energy input to facilitate the reaction.
It appeared that, in certain cases, most of the transformed output molecules, A, were maintained in miniature reaction centers, which spontaneously formed and decayed.
The Commerce Ministry's actions, it maintained, were in reaction to complaints it had received and were "based on the facts".
The reactions that comprise photosynthesis in plants and other organisms, for example, are not included, since the physiochemical context for these reactions is installed by the organism, and must be maintained in order for the reactions to continue (the photoreactions cease if the organism dies).
How are the nonactive reactions maintained in the metabolic network?
Tubes containing only the reaction mixture were maintained in the dark and served as control to reaction.
These domains seem to be faithfully maintained in mammalian MS. Because the reaction catalysed by MS regenerates cob(I alamin in every reaction cycle, the cofactor risks occasional oxidation to cob II)alamin with consequent inactivation of the enzyme (Ref. 114).
The temperature of the reaction was maintained in the range from 20 ± 1 to 60 ± 3 °C.
In other cells, it is maintained in its reduced form by reaction with glutathione, which can be catalysed by protein disulfide isomerase and glutaredoxins.
The reaction was maintained in the dark at room temperature for 1 h.
