So why do so many life-forms breathe oxygen?There are probably thousands of kinds of metabolisms, or chemical processes that maintain life, said Donald Canfield, a geobiologist at the University of ...

Therefore, special electron transporters exist in the mitochondria that help with the release of this high energy. Oxygen acts as a final electron acceptor in the chain and completes the process.

Our bodies need oxygen to survive, just like many other organisms. Oxygen molecules are used to create a molecular fuel called ATP for our cells in an organelle called the mitochondria; this process ...

Humans need oxygen molecules for a process called cellular respiration, which takes place in our cells’ mitochondria. Through a series of reactions called the electron transport chain, electrons are ...

They are weaker electron acceptors than oxygen. Both chlorine and fluorine gas are stronger oxidizers than oxygen [2] . In principle, we could get more energy from our food by using them as ...

XFELs show the final milliseconds of oxygen formation. Uppsala University. Journal Nature DOI 10.1038/s41586-023-06038-z ...

Nitrogen comprises around 78% of Earth's atmosphere, so why do most lifeforms breathe oxygen?
