光エネルギーに由来するエネルギーとは何ですか?🙇🏻‍♀️

V ●水の分解を放出して酸化された反応中心クロロフィルは,他の物質からeを受 け取りやすい状態になっている。この状態にある光化学系Ⅱの反応中心クロロフィル は、水からe を得て還元され,活性化する前の状態に戻る。e を失った水は分解され 酸素とHが生じる (図8-1)。 ●電子伝達 光化学反応で活性化された光化学系II から放出されたe,eの受け渡 electron transport system しをするタンパク質で構成された電子伝達系と呼ばれる反応系内を移動する。このと き同時に,Hがストロマからチラコイド内腔に輸送され,チラコイド膜をはさんで H*の濃度勾配が形成される(図3-2)。 電子伝達系を経たは,活性化された光化学 酸化 系Iの反応中心クロロフィルを還元する。こを待 ●NADPHの合成 活性化された光化学系 Iから放出された2個のeと,2個のH+に よってNADPが還元され, NADPHとHが生じる (図8-③)。 ●ATPの合成 光化学系Ⅱでの水の分解や, 電子伝達系におけるH+の輸送によって, チラコイド内腔のH+の濃度はストロマ側よりも1000倍程度高くなる。 こうして, チ ラコイド膜をはさんでH+の濃度勾配が形成される。 この濃度勾配に従ってH+ は ATP ATP synthase ごうせいこう そ 合成酵素を通ってストロマへ拡散し,これに伴ってATPが合成される (図8-④)。 こ こう さんか の過程は光リン酸化と呼ばれる。 photophosphorylation このような過程によって, 光エネルギーに由来するエネルギーがNADPHとATP に貯えられる。これらは, ストロマで起こる反応に利用される。

付箋で貼った2文がどうしてそのような訳になるのかわかりません。

た次の英文を読み, 設問に答えなさい。 (学習院 法学部 2022年) Society is everything. Many of us go through life thinking we are self-made and self-sufficient. Some may credit (or blame) their families for success or failure in life, but rarely do we think about (1) the bigger forces (that determine our destinies - the country we happen to be born in, the social attitudes common at a particular moment in history, the institutions that govern our economy and politics, and the randomness of just plain luck. These wider factors determine the kind of society in which we live and are the most important determinants of our human experience. 2 Consider an example of a life in which society plays a very (X) role. In 2004 I spent time with a family in the Ecuadorian Amazon*. Antonia, my host, had twelve children, and her oldest daughter was about to give birth to her first grandchild. They lived on the edge of the rainforest with no road, electricity, clean water or sanitation*. There was a school, but a considerable distance away, (Y) the children's attendance was irregular However, Antonia was a community health worker and had access via radio* to a doctor in a nearby town who could provide advice to her and others. Apart from this service (arranged by a charity), she and her husband had to be completely self-reliant gathering food from the forest, educating their children on how to survive in their environment. On the rare occasions when they needed something they could not find or make themselves (like a cooking pot), they searched for bits of gold in the Amazon, which they could exchange for goods in a market at the end of a long journey by boat. 3 This may seem like a very extreme and distant example, but it serves to remind us how accustomed we are to the things that living collectively gives us infrastructure, education and health care, laws that enable markets in which we can earn incomes and access goods and services. Antonia and her daughter promised to name the baby (they were Minouche, (2) which was a great honour. I often wonder what kind of life that other Minouche will be having as a result of being born in a very different society. V+ re expecting The way a society is structured has profound consequences for the lives of those living in it and the kinds of opportunity they face. It determines not just their material conditions but also their well-being, relationships and life The structure of society is determined by institutions such astical and legal systems, the economy, the way in which family and community life are organized. All societies choose to have some things left to individuals and others determined collectively. The rules governing how ? those collective institutions operate form what might be called the social contract, which 1 believe is the most important determinant of the kinds of lives we lead. Because it is so important and because most people cannot easily leave their societies, the social contract requires (Z) of the majority and necessary changes ás circumstances change. VF vf ⑤We are living at a time when, in many societies. people feel disappointed by the social contract and (3) the life it offers them. This is despite the huge gains in material progress the world has seen over the last 50 years. Surveys Social contract people

fについてです 解説が載っていなかったため質問しています、。 なぜ、③を選ぶことができるのでしょうか?

Long-s doctrin holds that we are protected from fungi not just by layered immune defenses but ( e ) we are mammals*, with core temperatures higher than fungi prefer. The cooler outer surfaces of our bodies are at risk of minor assaults-think of athlete's foot*, yeast infections, ringworm*-but in people with healthy immune systems, invasive* infections have been ( f ). That may have left us overconfident. "We have an enormous (g) spot," says Arturo Casadevall, a physician and molecular microbiologist at the Johns Hopkins Bloomberg School of Public Health. "Walk into the street and ask people what are they afraid of, and they'll tell you they're afraid of bacteria, they're afraid of viruses, but they don't fear dying of fungi." Ironically, it is our successes that made us vulnerable*. Fungi exploit damaged immune systems, but before the mid-20th century people with impaired immunity didn't live very long. Since then, medicine has gotten very good at keeping such people (h), even though their immune systems are compromised by illness or cancer treatment or age. It has also developed an array of therapies that deliberately suppress immunity, to keep transplant recipients healthy and treat autoimmune* disorders such as lupus* and rheumatoid arthritis*. ( i ) vast numbers of people are living now who are especially vulnerable to fungi. Not all of our vulnerability is the fault of medicine preserving life so successfully. Other ( j ) actions have opened more doors between the fungal world and our own. We clear land for crops and settlement and perturb* what were stable balances between fungi and their hosts. We carry goods and animals across the world, and fungi hitchhike on them. We drench crops in fungicides* and enhance the resistance of organisms residing nearby. (s) ELSE

Canned Bread to Feed the rid Have you ever heard of canned bread? This specially pa bread is designed as emergency food. When you open the can tastes as delicious as freshly baked bread. The idea of canned bread originated in the Great Hans Awaji Earthquake of 1995. Immediately after the earthqua a baker named Akimoto Yoshihiko baked 2,000 rolls and s them to the victims. A few days later, he got bad news. Half the rolls went bad before they could be distributed to people need. Therefore, they were thrown away. Akimoto G1 disappointed to hear that. G1 G1 A little while later, one of the earthquake victims said to hi "It was so depressing to have only hard biscuits to eat. I'd like to create bread that keeps for a long time but stays saf G1 Akimoto decided to rise to the challenge. 72 1. What did Mr. Akimoto do immediately after the earthquake? 2. What happened to the rolls that Mr. Akimoto sent? 3. What did Mr. Akimoto decide to create? Opinion 1. Have you ever eaten canned bread? If you have, how did it taste? If you haven't, what do you think it tastes like? go bad ex. The milk will go bad if you don't put it in the fridge. rise to the challenge ex. Our team rose to the challenge and won the tournament.
