下列4支试管中分别含有不同化学物质和活性酵母菌细胞制备物.在适宜温度下,会产生CO2的试管有
(1)葡萄糖+细胞膜已破裂的细胞 (2)葡萄糖+线粒体
(3)丙酮酸+线粒体 (4)葡萄糖+细胞质基质
A (1)(2) B (1)(3)(4)
C(2)(3)(4) D(1)(4)
要解释为什么的哟
下列4支试管中分别含有不同化学物质和活性酵母菌细胞制备物.在适宜温度下,会产生CO2的试管有(1)葡萄糖+细胞膜已破裂的细胞 (2)葡萄糖+线粒体(3)丙酮酸+线粒体 (4)葡萄糖+细胞质
选 B
(1)细胞膜破裂,葡萄糖任然可以正常分解,产生CO2;
(2)线粒体不能直接分解葡萄糖,所以不可以产生CO2,需要先在细胞质基质中分解为丙酮酸才能进入线粒体继续分解;
(3)丙酮酸可以进入线粒体,分解产生CO2;
(4)葡萄糖可以在细胞质基质中无氧分解,产生CO2.
B
首先你需要搞清楚呼吸作用在哪几个阶段会释放CO2。
对于有氧呼吸,第一阶段在细胞质中葡萄糖分解为两分子丙酮酸,少量能量,少量质子氢,没有CO2
第二阶段丙酮酸进入线粒体分解释放出大量CO2和质子氢及少量能量
第三阶段质子氢进入呼吸链,产生大量能量
对于无氧呼吸,都发生在细胞质中,分为乳酸发酵和酒精发酵,其中植物主要是酒精发酵,这个阶段也有CO2释放。

好了,现在看选项:1.葡萄糖+细胞膜已破裂的细胞肯定可以的,细胞膜劈裂,葡萄糖直接完成整个有氧呼吸过程
2.葡萄糖+线粒体,不可以。葡萄糖无法直接进入线粒体参与呼吸作用
3.丙酮酸+线粒体,丙酮酸进入线粒体参与呼吸作用第二三阶段,可以的。
4.葡萄糖+细胞质基质,这个可以发生无氧呼吸,即酒精发酵,产生CO2

Dust collection pipe down the tower wind up the transformation pressure
Closed airlock and a 4-72-5A-type fan to complete the mentioned materials. Radial spines clear nail down by the drum machine and clean wool clean wool MQR a 500B-based machine completed, and the recycling of dust Shaq dragon twisted cage by the transmission tower down by the stick of the drum machine to clean up clear down. The process on a sunny day, air humidity, hours, work, dust collection pipe down the tower without clogging; in rainy days,mbt chaussures paris, air humidity, dust collection pipe down the tower is easy to clogging phenomenon, especially in the rainy block 1MR a stripped down 144D machine 2.

Twisted cage cage 1 14 twist and dust tower velvet cotton linter waste recycling flow chart aoo4 ~ mouth dish foot (feet) (2) |, Dan ridicule the quality of the packaging of lint cotton directly affects the quality. Packed bales of cotton bag will cause the collapse grin silk, cotton bag that looks irregular, Lu Bai place likely to cause pollution, and even affect cotton quality. Cotton seed processing is the process of rolling out the lint, seed cotton in a cotton gin in this process is a clear one set of cotton a leather package, which sets the use of cotton is cotton dust collection cages, the cotton gin, skin cleanser machine blowing air out of the cotton fiber separated by Some dust,franklin marshall paris, leaf debris with the air sucked out through the mesh, cotton fibers from cotton dust collection cotton roll cage and set aside by the pressure of compressed cotton rolls made of cotton sheets, cotton Road and then drip drip along the baler. Set of cotton dust suction cage with unilateral and bilateral suction in two forms. Unilateral set of cotton dust suction cage, if the air pressure with a large amount of cotton fiber will focus on the suction outlet side of the (new bilateral air suction Dongguo Guang Wang exception). If the tendency to set aside cotton, cotton roll, and not only damage to the pressure roller gear aside cotton, dust will damage the mesh cage, and will eventually result in its breaking bale strapping wire (hereinafter referred to as collapse wire). First, because analysis of the amount of air pressure as the wind turbine too large cage attached to the surface of cotton dust layer thickness is inconsistent, the suction inlet side of the thick layer of cotton, cotton layer away from the suction outlet side than the book, while thick side of the book will be a piece of cotton, Cotton Road by drip feeding balers, resulting in a density of cotton bag, a density, so that the weight of bale size of the first generation, after the bale stack on by the wind and sun, cotton stretch increases, resilience, density of a cotton stretch over the wire should be subject to if the pressure on the bale wire binding will Bengduan. Second, for these reasons should be taken to the humidity, so the pipe would increase the proportion of the fibers, that ratio has increased co} Kun. As resistance increases, the wind speed is relatively reduced. As the wind speed decreases, the material deposition occurs, the pipeline will cause severe congestion. To solve the problem of pipe blockage and deposition, the pressure must be increased and the wind pipe, but 4-72-12C after the fan speed must be 30kW, or 57kW motor, increase energy,ralph lauren pas cher, and the existing process 4-72-- 5A fans have surplus energy, so the transformation: measures 1. With the correct amount of fan air pressure, so evenly distributed set of cotton dust in the cage mesh, in order to facilitate uniformity of cotton fibers inhaled. 2. Set of cotton dust suction outlet side of the cage away from the open door air volume air pressure adjustment, effective up wind, thick book to ensure that the same piece of cotton. 3. Side of the drip thick piece of cotton Cotton Road due to the booster, little inclined to make cotton sheet evenly into the baler. In taking these measures, the weight of bales will naturally reduce the size of the first,abercrombie france, if qualified in the case of wire pull, will greatly reduce the collapse of cotton yarn package rate.

Of the wind pipes, the wind cleared the introduction of bars tumble down machine, then a velvet mouth sealed, twist in the row of miscellaneous converted a closed cage axis wind device, and then sucked down the wind pipe pipe down and butt up. Approach to pressure feed tube to the suction pressure up down the wind, which is characterized by increased air density inside the tubes, the viscosity becomes large, mixing ratio also increased. Using this feature increases the pressure inside the pipe and wind speed, the tower down into the dust collection down! Ken Ji Fort Fort Fort Fort Da Wen fell bad! Plastic look is Chu Chu is the main summer is a Triple Man Chu is the mains and set down machine. This approach can do pressure to send long-distance transmission, it is combined with suction feed type for the hybrid pneumatic conveying equipment, where the dust is mainly responsible for the delivery of the tower down recycling tasks. Between the absorption characteristics of hybrid delivery type and pressure fed between: to take this program can not only solve the pipeline problem of insufficient wind speed and pressure, can reduce energy consumption, cost savings, interested colleagues may wish to try.
