Sentences with phrase «oxygen molecules during»

Without enough red cells to grab oxygen molecules during their trip through the lungs, the kitty is in trouble.
Grossman explains: «One theory that we are exploring is that under heat - stress conditions the corals eject the algal symbionts at night in order to avoid the production and accumulation of photosynthetically - derived toxic oxygen molecules during the day.
It has been theorized that the major cause of bleaching is the result of chloroplast damage due to heat stress, which results in the production of toxic, highly reactive oxygen molecules during photosynthesis.

Not exact matches

The idea was that during the day, oxygen molecules are ionised by ultraviolet light from the Sun to form O2 + ions.
This is surprising since it means that toxic oxygen molecules formed in heat - damaged chloroplasts during photosynthetic reactions during the light are likely not the major culprits that cause bleaching.
Moreover, small amounts of singlet oxygen produced during metabolic reactions can act as a local signaling factor that oxidizes and modifies target molecules, but the underlying mechanisms are poorly understood.
During the day, ultraviolet rays from the sun split oxygen, nitrogen, and other molecules in the upper atmosphere.
During laboratory tests, Giapis showed that when these water particles hit the comet's surface, they attach themselves to the oxygen atoms contained in other molecules, such as iron oxide (rust) and silicon dioxide (sand).
Composed of carbon, hydrogen, nitrogen and oxygen atoms (forming the CH3NCO molecule) a tragic methyl isocyanate gas leak caused thousands of deaths and injuries during what is considered to be the deadliest industrial accident in history — the Indian 1984 Bhopal disaster.
Mononuclear cells from the blood were isolated during the OGTTs to analyze if these cells were producing molecules known as ROS (reactive oxygen species).
Research suggests that Vitamin C is a highly effective antioxidant and that small amounts can protect essential molecules in the body from free radical damage and reactive oxygen species generated during normal metabolism, as well as through exposure to toxins and pollutants.
* It is also a highly effective antioxidant that can protect the body's cells and molecules from damage by free radicals and reactive oxygen species generated during normal metabolism and exposure to environmental stressors.
* It is also a potent antioxidant that can protect the body's cells and molecules from damage by free radicals and reactive oxygen molecules generated during normal metabolism and typical environmental exposures.
* It is also a highly effective antioxidant that can protect the body's cells and molecules from damage by free radicals and reactive oxygen molecules generated during normal metabolism and exposure to environmental stressors.
As congestive heart failure progresses, the formation of «free radicals» (reactive molecules created during oxygen metabolism) increases heart cell damage.
To make it even more clear: I kept repeating that:» during the day, in the upper atmosphere — one CO2 molecule can not pas heat to another — BECAUSE THERE ARE THOUSANDS OF oxygen & nitrogen atoms IN - BETWEEN, as perfect insulators.
Globally averaged, Earth's atmosphere has warmed about 0.45 Celsius (about 0.82 ° F) during the almost one - third of a century that sensors aboard NOAA and NASA satellites have measured the temperature of oxygen molecules in the air.
I am assuming that during Ice Ages, CO2 was very low due to the oxygen being locked in ice which is H2O, that is, one oxygen molecule and two hydrogen.
Oxygen is produced through the splitting of water molecules during photosynthesis.
