Quote What can happen is that during respiration reactive oxygen species are generated. This is mostly due to leakage from the ubiquinon pool as part of the aforementioned oxidative phosphorylation. These species are kind of aggressive and can indeed lead to damages, unless they are dealt with the many mechanisms in cells to neutralize them (e.g. superoxide dismutases, catalases, peroxidases etc.). Quote

The oxiadation in cell biology that damage cells and DNA because of energy and oxygen reacting. Well oxiadation is bad?

Can someone here explain this quote better?
