Abstract:

New insight into the biochemical mechanism of invertebrate anoxibiosis made possible the calculation of the free-energy changes associated with the generation of high-energy bonds in nucleoside triphosphates (ATP, GTP, ITP) under anoxic conditions. The values obtained are compared with thermodynamic data of aerobic and fermentative energy production, and indicate a selection towards increased energetic efficiency of biochemical pathways leading to less toxic and readily excretable end products in anoxibiotic invertebrates. The thermodynamic model is mainly based upon a metabolic scheme elaborated on intertidal bivalves by de Zwaan et al, benthic oligochaetes and fresh-water bivalves. It may provide a general hypothesis for the energetic processes which operate in a variety of ecological and taxonomic groups of anoxibiotic animals.
