The activities of cytosolic oxidoreductases (malate and lactate dehydrogenases) and the level of ATP production in the hypoxic resistive tissues of Scorpaena porcus Linnaeus, 1758 were studied. It was found that “oxyphilic” tissues (structures of the brain, gills) are pre-adapted to hypoxia, since under normal conditions they had high MDH activity and an increased MDH/LDH ratio, the value of which was 10 to 20 times higher than that in the liver and white muscles. Moreover, in the relatively “young” brain divisions (forebrain, diencephalon, midbrain) the aerobic pathway of carbohydrate metabolism predominated. The ATP content decreased in a line of examined tissues as follows: white muscles → liver → medulla oblongata → gills → forebrain, diencephalon and midbrain. The ATP level in white muscles was an order of magnitude higher than in “oxyphilic” tissues and it probably served for the provision of throwing strategy for hunting of bottom predator.

黑海R(Scorpaena porcus)(Scorpaenidae)中能量代谢酶活性和ATP含量的组织特征

Scorpaena porcus低氧抗性组织中胞质氧化还原酶的活性(苹果酸和乳酸脱氢酶)和ATP产生水平研究了1758年的林奈(Linnaeus)。发现“嗜氧”组织(大脑,腮等组织)已预先适应缺氧,因为在正常条件下,它们具有较高的MDH活性和较高的MDH / LDH比,其值比后者高10到20倍比肝脏和白肌的要好。此外,在相对“年轻”的脑部区域(前脑,间脑,中脑)中,碳水化合物代谢的有氧途径占主导地位。一系列检查的组织中的ATP含量降低如下:白肌肉→肝脏→延髓→腮→前脑,中脑和中脑。白肌肉中的ATP含量比“嗜氧”组织中的ATP含量高一个数量级,它可能有助于为捕食海底捕食者提供投掷策略。
