The molecule then becomes a recognition signal for phagocytic binding and removal of the expended cell.
Assuming that the amount of energy expended per cell produced is invariant and that electron transfer from NADH to S° yields no energy, a comparison of the numbers of cells produced per Fe(III) reduced during growth on ethanol versus growth on hydrogen is a comparison of the energy yields that accompany reduction of NAD by oxidation of ethanol versus oxidation of hydrogen.
Ectopic expression of the Notch1 or Notch2 intracellular domain was sufficient to induce SSEA-1+ cells and to suppress pNEB formation without expending Clara cells.
Thousands of pixels were printed, and thousands of words written, and at least a few hundred sub-editors' brain cells expended on such headlines as 'America's Next Top Waddle' and, um, 'Tyra Porkchops' (oh, come on, guys. What about 'Grand Banks'Spareare Tyra'?), and all because, as far as I can work out, her bottom and thighs looked a little bit big.
Since Haldane's day, a great deal of scientific effort has been expended on hydrogen fuel cells, but hydrogen-powered cars are still underpowered, unreliable, and costly.
Therefore, the isolated primary cancer cells generally need to be expended in number for the subsequent cell-based assays.
Updated, 6 08 p.m. | New Yorkers, your days of expending precious brain cells trying to determine whether that yogurt cup or plastic takeout container goes in the trash or the recycling bin have come to an end.
Molecules of glycerol are usually actively transported into fungal cells expending ATP, but facilitated diffusion of glycerol has also been observed (Fakas et al. 2009).
The induction of diverse nutrient import systems may be necessary for cells to harvest all available nutrients in the current growth media or could represent an example of carbon source foraging [55], where cells expend energy to broaden their search for alternative energy sources.
Therefore it is likely that cells expend considerable efforts to rein in the apoptosis-inducing behavior of RIP1 when death is not the desired outcome.
