Effects of the sea water osmoconcentration changes on oxidative processes in isolated gill of shore crab Carcinus mediterraneus Csrn

When gills isolated from the crab Carcinus acclimated to various diluted seawater osmoconcentrations , the oxygen consumption rate was salinity-dependent and considerably increasede as seawater concentration decreased. The results suggest that the portion of the energy liberated by the gill respiration is utilized by the gill Na, K-ATPase enzyme complex maintaining Na and K concentration gradients between the extracellular and intracellular compartments. We suggeast that electron transfer chain was blocked , and consequently oxidative capacity mediated via cytochrome oxidase was diminished.
