1 ウエヌクが出会った少女 [大阪教育大附高平野 制限時間 1回目: 20分 / 2回目(英文のみ) : 7分 This is the story of "Ue-nuku. Early one morning, before the sun was up, Ue-nuku was walking in the forest. He came to a lake. Two girls were swimming in the lake. They were girls of the sky. They were on earth for a little while. One _)( ) was the Rain-girl. 5 was the "Mist-girl, and ( Ue-nuku did not know who they were, but he knew that they were beautiful. They were so beautiful that 2[ he / how / know / marry / to /to/ wanted] one of them. But while he was watching, the sun came up. When the girls saw it was day, they were frightened. "We must 10 go!" they cried. "We are girls of the mist and rain. If the sun shines on us, we will die." While Ue-nuku watched, the two girls went slowly and softly back up to the sky. That night, Ue-nuku sat alone in his house. He said to himself, "Will I ever see the two girls again? They were so beautiful. I want to 15 marry one of them!" While he was thinking, the door of this house opened and the Mist-girl came in. “Ue-nuku, I have come to stay with you," she said. "But I can only stay at nighttime. When day comes, I must go back up to the sky. If the sun shines on me, I will die." The Mist-girl stayed all that night. Before the sun came up, she said 20 goodbye to Ue-nuku and went to her home in the sky. Ue-nuku did not like this. 4[ he/her/him / stay / to / wanted with all the time. One day, he said to himself, "I will put "mats over the door and window of my house. The Mist-girl will not know day has come. 25 She will think it is still night, and she will stay with me." That night, there were mats over the door and window of the house. "Day has not yet come," said Ue-nuku. "Stay with me." The Mist- )! I'm sure it is day by girl said, "What a 5 ( ) ( now." Ue-nuku said again, "Day has not yet come. Stay with me." Time passed, and the Mist-girl said a third time, "This night is too long. I'm sure it is day now." Before Ue-nuku could stop her, she

至急お願いいたします🚨 生物の質問です。 ミトコンドリアの経路についての説明だと思うのですが、電子オーバーフローモデルと電子分布モデルの違いを教えていただきたいです。 また、どういう仕組みなのか、何故このように電子が流れるのかも教えていただきたいです。 UQ poolはユ... Read More

(A) Electron overflow model (considered out-of-date) Alt UQ pool Alternative oxidase inactive. Alt No alternative pathway activity Cytochrome pathway unsaturated Cyt (B) Electron distribution model (reflects current thinking) UQ pool Cyt Alternative pathway active Cytochrome pathway saturated Alt Alternative oxidase active Alt UQ pool Cyt Cyt Figure 14.33 Two models for regulation of electron flow through the alternative oxidase. (A) In the electron overflow model, no appreciable electron transfer through the alternative pathway takes place until electron flow through the cytochrome pathway is at or near satu- ration. This could result from the effects of respirato- ry control, if the rate of mitochondrial ATP produc- tion exceeds its rate of utilization in the cytosol, or from some externally imposed stress, such as low temperature. Under such circumstances, the UQ pool becomes sufficiently reduced to allow electrons to flow through the alternative oxidase, the latter re- quiring that the UQ pool be 40% to 60% reduced to attain significant activity. (B) In the electron distribu- tion model, the alternative and cytochrome path- ways both show significant activity at low levels of UQ pool reduction, and electrons are distributed be- tween the two pathways on the basis of the relative activities of each pathway. The activity of the alter- native oxidase under these circumstances is thought to be regulated by the action of a-keto acids and by reduction/oxidation of the intermolecular disulfide bond, as well as by additional regulatory mecha- nisms not yet characterized.
