Mechanism and Physiological Role of Epidermal Amino Acid Transport in Marine Bivalves

Part of the Proceedings in Life Sciences book series (LIFE SCIENCES)


The tissues of marine bivalves are rich in free amino acid (FAA), and the regulation of the cellular concentrations of these solutes appears to be linked with isoosmotic volume regulation (Gilles 1979). In epidermal tissues, such as the cells of the gill, the concentration of amino acid often exceeds 70 mmol kg-1 wet weight, separated from surrounding seawater by a single plasma membrane. It is, therefore, reasonable that exchanges of amino acid between the gill and the environment could play an important role in the maintenance of cellular FAA concentrations, and consequently in overall solute balance and cell volume regulation in these animals.
