Nearly all energy production in living organisms is by oxidation reactions (fires are large oxidative embers)

Oxidation reactions produce, through complex intermediate steps, small energy packages that are more easily stored than a sudden combustion oxidation. The slow and controlled production of energy in a nuclear power plant allows its use, a massive explosion produces the result that we know ... It’s the same thing in our bodies. These reactions are never 100% efficient, not all the energy produced is used as bio fuel. Indeed, during the intermediate stages, they induce a deterioration of cells and tissues by consuming about 10% of this energy. They cause significant “wear and tear” when there is no longer any compensation for these parasitic oxidations. The latter can be excessively used in pathological situations inducing inflammatory reactions, or simply during metabolic overproduction, or even simple intense and prolonged efforts.
