"Brexit" is a more recent example. The word concisely explains that Great Britain exited from the EU. Lastly, can you guess the meaning of the word "snaccident"? Let's say you have a snack, such as a pack of cookies, and decide to eat just one cookie. However, you can't stop eating and finish the whole pack by accident. That's a "snaccident"!

For example, electric cars take more time to charge than gas-powered cars. Moreover, electric cars can run few distance. Onother reason is that electric cars cost a lot of money in the many situation. For example, people who use electric, cars usually sex charging places at the each houses, but they have to pay so much cash to do it, Also, they need to prepare too much money every month to charge electric Propte cash, For these reasons above, I believe that gas-powered cars will be replaced by electric cars in the near future. total: 179 words

(A) Electron overflow model (considered out-of-date) Alt UQ pool Alternative oxidase inactive.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