Effects of hypoxia and spawning on mitochondrial metabolism and bioenergetics of the blue mussel Mytilus spp. from the Baltic Sea

We studied the effect of short-term hypoxia (7 days) and spawning (pre-spawning, and 3 h and 72 h post-spawning) on mitochondrial respiration, reactive oxygen species (ROS) production, and energy budget of the mussels Mytilus edulis. The data set reports oxygen consumption, efflux of reactive oxygen species (H2O2), fractional electrol leak (ratio of H2O2 efflux to O2 consumption) in isolated mitochondria, as well as the biochemical composition and energy content of the gills and the digestive gland tissues, tissue energy demand (measured as the activity to the electron transport system) and cellular energy allogation (CEA) in the tissues of the mussels.本研究探讨了短期低氧（7天）与产卵进程（产卵前、产卵后3小时及72小时）对紫贻贝（Mytilus edulis）的线粒体呼吸、活性氧（reactive oxygen species, ROS）生成及能量收支的影响。本数据集包含分离线粒体的耗氧量、活性氧（H₂O₂）外流、电子漏分数（H₂O₂外流与耗氧量的比值）相关数据，同时涵盖贻贝鳃与消化腺组织的生化组成、能量含量，以及上述组织的组织能量需求（以电子传递系统活性表征）和细胞能量分配（CEA）相关数据。
