Unlike the oxygen in Earth's atmosphere, Europa's is not of biological origin.

The use of oxygen as part of the process for generating metabolic energy produces reactive oxygen species.

The accumulation of oxygen One of the most important events of the Proterozoic was the accumulation of oxygen in the Earth's atmosphere.

Oxygen dependent intracellular When a phagocyte ingests bacteria (or any material), its oxygen consumption increases.

The increase in oxygen consumption, called a respiratory burst, produces reactive oxygen containing molecules that are anti microbial.

This method of killing invading microbes by using the reactive oxygen containing molecules is referred to as oxygen dependent intracellular killing, of which there are two types.

Eutrophication is an increase in the concentration of chemical nutrients in an ecosystem to an extent that increases in the primary productivity of the ecosystem.

This enzyme transfers electrons directly from ubiquinol to oxygen.

Xanthophylls contain their oxygen either as hydroxyl groups and or as pairs of hydrogen atoms that are substituted by oxygen atoms acting as a bridge (epoxide).

Aluminium oxide is a chemical compound of aluminium and oxygen with the chemical formula 23.

In the language of valence bond theory, the hybridization at oxygen is sp3.

It fits into the environment. It is the environment.

Physical exercise During exercise, oxygen consumption can increase by a factor of more than 10.

The oxygen compounds are toxic to both the invader and the cell itself, so they are kept in compartments inside the cell.

The reactivity of the iron center may be improved by the presence of the phenolate ligand of Tyr357 in the fifth iron ligand, which can assist in the oxidation of the Fe(III) to Fe(IV).

There are blood vessels near the surface of the skin and when a frog is underwater, oxygen diffuses directly into the blood.

Some species of frog have adaptations that allow them to survive in oxygen deficient water.

Heliox, a mixture of helium and oxygen, may also be considered in severe unresponsive cases.

In this disease there is an abnormality affecting different elements of oxygen dependent killing.

In plants, algae, and cyanobacteria, photosystem II uses light energy to remove electrons from water, releasing oxygen as a waste product.

For example, in E. coli , there are two different types of ubiquinol oxidase using oxygen as an electron acceptor.

Various triggers for the Cambrian explosion have been proposed, including the accumulation of oxygen in the atmosphere from photosynthesis.

Originally, the term antioxidant specifically referred to a chemical that prevented the consumption of oxygen.

The tracheoles, found at the end of the tracheal tubes, are insinuated between cells and carry oxygen throughout the body.

The superoxide is converted to hydrogen peroxide and singlet oxygen by an enzyme called superoxide dismutase.

Electron transitions from these levels in doubly ionized oxygen give rise to the 500.7 nm line.

We're defined by our environment and our interaction with that environment by our ecology.

Quantity Enzyme production (transcription and translation of enzyme genes) can be enhanced or diminished by a cell in response to changes in the cell's environment.
