| Reactive oxygen species are generated under various biotic and abiotic stresses, and trigger cell death. |
| Some bacteria are able to switch from enzymes using oxygen as a terminal electron acceptor to enzymes using alternative electron acceptors. |
| It obeys the law of conservation of mass since the amount of phosphorous and oxygen remains the same throughout the reaction. |
