This energy is used by the cell to carry out endergonic reactions.
These anoxic embryos appear to be exceptions to a central paradigm of cell biology; namely, that a constant and substantial flow of free energy is required to maintain cellular structure and function (including the requirement for macromolecular turnover); these major endergonic processes in cells are apparently not in evidence in long-term anoxic Artemia embryos.
(19) In a second approach, biological organization is a process that couples endergonic processes to the exergonic ones, therefore thermodynamically uphill processes to downhill ones.
The active movement of ions requires energy and is thus an endergonic reaction.
The first step of C[O.sub.2] reduction is an endergonic reaction that oxidizes ferredoxin and produces formylmethanofuran.
