Aerobic metabolism, octopine production and phosphoarginine as sources of energy in the phasic and catch adductor muscles of the giant scallop Placopecten magellanicus during swimming and the
1. 1. The energy contributions of aerobic metabolism, phosphoarginine, ATP and octopine in the adductor muscles of P. magellanicus were examined during swimming and recovery. 2. 2. A linearExpand

Metabolic Adaptations To Environmental Anoxia in the Intertidal Bivalve Mollusc Mytilus Edulis L
Many invertebrate species are able to withstand periods with interrupted oxygen supply that may extend over days. These so-called euryoxic organisms show metabolic adaptations different from thoseExpand

The role of amino acids in anaerobiosis and osmoregulation in bivalves
The role of free amino acids as solutes for cell volume regulation in marine molluscs under salinity stress is well established. Under hypoosmotic stress the intracellular concentrations of aminoExpand

Differential sensitivities to hypoxia by two anoxia-tolerant marine molluscs: A biochemical analysis
The metabolic responses to a series of low oxygen tensions were compared for two species of Mediterranaean bivalves,Mytilus galloprovincialis andScapharca inaequivalvis. Whereas both species haveExpand

Physiological and biochemical aspects of the valve snap and valve closure responses in the giant scallopPlacopecten magellanicus
Summary1.The giant scallopPlacopecten magellanicus responds to stimulation with starfish extract by snapping the valves in a series of rapid adductions. After approximately 25–35 adductions, theExpand
