当八年级在学习“血液循环的器官”论题时通常是用将血液摇匀的方法来演示静脉血变为动脉血的,其结果是发生了血液被空气中的氧所氧化。论文建议以用酵母的生活活动为基础的氧合血红蛋白复元的生物学方法。当时学生们就有可能观察到氧合血红蛋白复元过程与复元的血红蛋白氧化的动态。实验是用面包酵母特性来复元氧合血红蛋白的。巳复元的血红蛋白是极易重新变为氧合血红蛋白(要 When the eighth grade was studying the topic of “organs of the blood circulation,” it was common practice to shake the blood to demonstrate that venous blood was changed to arterial blood. As a result, the blood was oxidized by the oxygen in the air. The paper suggests a biological approach to the recovery of oxy-hemoglobin based on the living activity of yeast. At that time, students may observe the dynamic process of oxygenated hemoglobin recovery and hemoglobin oxidation of sevoflurane. The experiment uses baker’s yeast properties to reconstitute oxy-hemoglobin. Already hemoglobin has been restored to oxygenated hemoglobin (want
