Variability of respiration and pyridine nucleotides concentration in oceanic zooplankton
We have studied the in vivo respiratory oxygen consumption (RO2) and the potential respiration rates (Φ), measured by the enzymatic activity of the electron transport system (ETS), in epipelagic marine zooplankton from several marine systems. Furthermore, we have determined the intracellular concent...
