Inert

Definition

Inert describes a substance that does not readily react with other substances under normal conditions. In biology, inert substances often play a role in maintaining stable environments within cells and organisms.

5 Must Know Facts For Your Next Test

1. Noble gases are classic examples of inert elements due to their complete valence electron shells.
2. Inert substances can be used as controls in experiments because they do not interfere with the reactions being studied.
3. Carbon dioxide is considered relatively inert in many biological processes but can become reactive under certain conditions.
4. Inert compounds like nitrogen gas (N2) have strong triple bonds that require significant energy to break, making them less reactive.
5. Many biomolecules are stabilized by being associated with inert substances, such as proteins binding to non-reactive metal ions.
