Chemistry of Energy Use Metabolism The total of all the chemical reactions occurring in living organisms is  metabolism  and the  sequences in which they occur are the  metabolic pathways . Cells can metabolize because they are  isolated systems, separated from their environment by  membranes . Organisms, and the cells of  which they are composed, use enzymes to regulate the reactions and utilize energy carriers to move  energy among the parts of the system. Metabolic reactions are linked so that exergonic reactions  supply energy for the endergonic.  Oxidation–reduction reactions Most of the energy exchanges in plants are chemical reactions that involve the exchange of energy  between one set of chemical bonds and another. These, for the most part, are  oxidation-reduction  reactions (commonly called  redox  reactions). In oxidation, electrons are  lost  from an atom or
