(A) Electron overflow model (considered out-of-date) Alt UQ pool Alternative oxidase inactive.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

「,well behind 」の部分の構造、意味を教えてください。

[Review] Back in the late sixties, thinkers on both sides of the Atlantic were troubled by problems which may seem strange to us today: they were worried that the leisure age which they believed was fast approaching would leave people with too much time on their hands. They were worried that the work ethic was losing its grip on a new rebellious generation and they pondered how they would motivate people to work. They needn't have worried. The much-predicted "leisure age" promised by technology has not materialized. In fact, quite the reverse: people are working harder than ever. There is less leisure time and, most surprising of all, the very workers with the greatest bargaining power are choosing to work the hardest. The problem is the burnout of white- collar Britain. For over a century, the average number of hours spent working over a lifetime slowly declined in Britain. The historian James Arrowsmith has calculated that in 1856 our ancestors put in 124,000 hours over a 40-year working life and, by 1981, it was 69,000. There it remained for a decade, but in the early nineties it began to increase again. On average full-time British workers now put in 80,224 hours over their working life, and that figure rises to 92,000 for those on a 50-hour week, which is common among the self- employed, the skilled, and professional and managerial workers. Many are working the kind of hours that would have been familiar to factory workers in the middle of the 19th century. The only difference is that now it's the bosses who are more likely to be putting in the hours than those on the shop floor. Britain has followed a US model of all work, no play, in contrast to continental Europe. Full-time workers in Britain now work the longest hours in Europe an average of 43.6 hours per week compared with an EU average of 40.3. Even more marked is the difference in holidays between Britain and continental Europe; the UK has, on average, 28 days a year, well behind France with 47, Italy with 44 and Germany with 41. Add the difference in weekly hours and holidays and it amounts to the British working almost eight weeks a year more than their European counterparts. -
