Sentence examples for electron availability from inspiring English sources

One factor limiting biosolar hydrogen (H2) production from cyanobacteria is electron availability to the hydrogenase enzyme.

A possibility to further improve electron availability would be the activation of an oxidative pathway, e.g. the oxidative pentose phosphate pathway in Rps.

So we suggest that temperature effects on enzyme activity may need to be considered, as well as temperature effects on electron availability.

The model we present here, initially proposed in Harrison et al. (2013), builds on Niinemets' work but differs in one fundamental respect: it links isoprene emission to the electron availability for isoprene emission, relative to the needs of CO2 assimilation.

Using data from Medlyn et al. (2000) and references therein, we checked variations with temperature of electron availability among isoprene emitting species at 1000 µmol m−2 s−1 PAR (Fig.  11).

Our model implies that the allocation of reducing power to this pathway occurs under those conditions when electron availability is in excess, which fortuitously occurs during stress events when isoprene biosynthesis and emission is advantageous to the plant (e.g. Sharkey et al., 2001; Vickers et al., 2009).

Recent results indicate that redox processes are not completely controlled by the sequential reduction chain (that is electron acceptor availability) but that electron donor availability may be an important regulator.

The relative sizes of redox zones are determined by a complex interplay of factors including temperature, hydrology, lake turnover or mixing and macrophyte and macrofaunal activity, which together influence the balance of organic matter and terminal electron acceptor availability.

Our hypothesis was that only sites which are limited in their electron donor availability (low concentrations of dissolved organic carbon (DOC)) follow the concept of the sequential reduction chain.

Thus, in these anaerobic incubations, electron acceptor availability limited a priming effect on the comparably refractory peat, and importantly, input of labile carbon from J. effusus did not compromise the preservation of peat.

These results suggest that in-situ CH4 production is tied to alternative electron acceptor availability, and that organic layer thickness is a good predictor of biogeochemical controls on CH4 fluxes in wet-sedge Arctic Alaskan tundra.
