(A) Electron overflow model (considered out-of-date) Alt UQ pool Alternative oxidase inactive.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

humans. "We were able to identify one of the many molecular features that likely shape behavior," she adds. ** hol boquete es Though the origins of the dog/human partnership remain unknown, it's becoming increasingly clear that each species has changed (during our long years header The physical differences between a basset hound and wolf are obvious, but dogs have also changed in ways that are more than skin (or fur) deep. One recent study shows how by bonding with us and learning to work ogether with humans, dogs may have actually become worse at working together Their pack lifestyle and mentality appear to be reduced and are far as a species. less prevalent even in wild dogs than in wolves. But, Yale's Laurie Santos says, dogs may have compensated in other interesting ways. They've learned to use humans to solve problems. "Several researchers have presented dogs and wolves with an impossible problem (e.g., a puzzle box that can't be opened or a pulling tool that stops working) and have asked how these different species react," Santos explains. Researchers have found that wolves try lots of different trial and error tactics to solve the problem - they get at it physically. But at the first sign of trouble, dogs do something different. They look back to their human companion for help. This work hints that dogs may have lost some of their physical problem-solving abilities in favor of more social strategies, ones that rely on the unique sort of cooperation

（4）の thisをある語に置き換えるという問題で模範解答はboiling （their potatoes/them）ですが to boil their potatoesではダメですか？

東京 suggesting a risk linked to, cooking some starchy foods in the microwave, including PANAS cereals and root vegetables. nová nayo si lo era When Betty Schwartz, professor of nutritional sciences at the Hebrew University of Jerusalem, saw her students heating jacket potatoes in the microwave on their lunchbreaks, she noticed small crystals inside their potatoes. rob When she analysed them, she found they were high in the chemical acrylamide, which can be a natural by-product of cooking. Schwartz asked her students to boil their potatoes instead, and found that this didn't create acrylamide, which she says forms in higher temperatures in the microwave. all not ber pb This is a concern because animal studies have shown that acrylamide acts as a carcinogen because it interferes with cell's DNA, but evidence in humans is limited. There is some research to suggest that microwaves are more favourable to the growth of acrylamide than other methods of cooking. "At 100°C (212°F), there's enough energy to alter the automatic joints between molecules to produce a molecule with much higher energy, which can react with DNA, which induces mutations," says Schwartz. "When you have many mutations it can produce cancer." Animal studies have shown this to be the case with acrylamides. 英語 9 the microwave.

Do companies need to improve the noy they treat their workers? and I think that companies need to improve the way they treat their workers and I have two reasons to support my opinion. The first reason is that companies should give same oppotunities to female. Some companies discriminate between male and female. For example, they decrease the number of recruies of female, and employees divided works such as cleaning and dest work between man women so they have to aim the mole female equality. The second reason is that work-life balance is serious issue by employees because they spend too much time to work. Companies should make holiday and decrease overtime work. If they do that, workers will balance work and life 110 for the two reasons mentioned above that companies need to improve the way they treat their workers. 90
