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... 続きを読む

(A) Electron overflow model (considered out-of-date) Alt UQ pool Alternative oxidase inactive.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.

高校レベルの物理の問題です。 答えは出したのですが、解答と合わなかったので最後の問題の解き方を教えてください。

空気抵抗とは空気との接触により運動を妨げようとする力のことであり、運動している物体の速さ (速さの1乗) に比例する粘性抵抗と速 さの2乗に比例する圧力抵抗がある。 雨が圧力抵抗のみを受けながら鉛直下向きに落下する様子を考える。 圧力抵抗の比例定数を重 力加速度の大きさをg [m/s²]として以下の問に答えよ。 V 問31 鉛直下向きを正として雨の加速度をa [m/s'] としたとき、 速さ [m/s]で落下している雨滴の運動方程式はどのように記述され るか。 適切なものを1つ選べ [31] ① ma = mg + kv² (2) ma=-kv (3) ma = -kv² (6) ma=mg- ・kv (7) ma = mg-kv² ⑧ ma-mg 問32 比例定数kの単位はSI単位でどのように表されるか。 適切なものを1つ選べ。 [32] ① N·m ②N・s ③kg·m ⑥ N/m ⑦ N/s ⑧kg/m ①kmg mg k ② 月 33 雨滴は地表付近では等速度運動をする。 そのときの速度 (終端速度) Pt [m/s] として適切なものはどれか。 1つ選べ。 [33] mg -1 (半径に反比例) img k 5 1 (半径の1乗に比例) ④kg's ⑨kg/s 1km g 30 (半径に関わらず一定) 4 ⑧ 0 34 圧力抵抗の比例定数kはp を空気の密度、S を物体の断面積として、以下の関係がある。 x=2/cos CpS 4 ma = kv 9 ma = mg - 12/1 (半径の平方根に反比例) ⑤m/s² ⑩ 単位無し ここで、Cは物体の形状に依存する係数であり、 球の場合はおよそ 0.5 となる。 雨滴の形状が球だとして、終端速度は雨滴の半径の何 乗に比例するか。 適切なものを1つ選べ。 [34] ⑥⑥/12 (半径の平方根に比例 62 (半径の2乗に比例) ⑤ ma=kv² 10ma = mg + kv kv²=mg V = long fals い JAL = der²tu Img_ 11 4mg erin 4mg en F√ √
