Teaching biophysics I. The specific interactions: the sine qua non processes of life

" The manifestation of life, in all its aspects, is the result of an enormous number of specific biophysical and biochemical molecular interactions taking place ceaselessly into cells, in a highly ordered manner both spatially and temporally. Frequently, a product of any reaction, is not a final compound, but the initial reactant of another reaction taking place in a precise location and at right time into the intricate cellular reactions network.
