Example sentences for: photons
How can you use “photons” in a sentence? Here are some example sentences to help you improve your vocabulary:
A variety of environmental small molecules, namely, nutrients, xenobiotics and first messengers are recognized by cells, with the help of specialized protein sensors on their surfaces [ 1 2 ] . Additionally cells also use protein-bound small molecules, such as FAD, cinnamic acid, tetrapyrroles and heme as sensors of photons and the ambient redox states [ 3 4 ] . Within cells, small molecules, such as cyclic nucleotides, are used as intracellular messengers to transduce signals arising from a variety of stimuli [ 1 2 ] . Over the past few years a combination of protein sequence analysis and biochemical studies have revealed several unifying principles that govern the recognition of small molecules by cells [ 4 5 6 7 8 9 ] . A significant component of small molecule-protein interactions is mediated via a relatively small set of ancient conserved protein domains that bind their ligands using specialized pockets [ 4 10 ] . Certain protein folds have given rise to several large superfamilies of ligand-binding domains.
Synechocystis PCC6803 cultures were grown autotrophically in BG-11 medium essentially as described by Williams [ 9 ] . Specifically, 500 mL cultures were grown in flat (4 cm across the light path) Bellco tissue culture flasks at 30°C under white light fluorescent illumination (Cool White ®, General Electric) with an incident intensity of 80 μmoles photons m -2s -1.
Unless otherwise noted, plants were grown under 60 to 80 μmol photons m-2 s-1 continuous fluorescent light, at a temperature of 21 to 25°C.
If you turn on your television and tune it between stations, about 10 percent of that black-and-white-speckled static you see is caused by photons left over from the cosmogonic event.
GFP-protein molecules were excited by 488 nm photons produced from an Argon ion laser (Melles Griot) and a 100× (NA = 1.65) objectiv (Olympus).
