甲状腺细胞可以将氨基酸和碘合成甲状腺球蛋白,并且将甲状腺球蛋白分泌到细胞外,其过程如下图所示。下列叙述错误的是(   )

A:若含18O的氨基酸在甲状腺细胞内的代谢过程中产生了H218O,那么水中的18O最可能来自于氨基酸的—COOH

B:细胞内的碘浓度远远高于血浆中的碘浓度,这表明a是主动运输过程

C:与甲状腺球蛋白合成和分泌有关的主要细胞器是核糖体、内质网、高尔基体、线粒体

D:与右图中③不直接相通,但膜成分最为相似的是高尔基体,用含3H标记的氨基酸注射到该细胞中,则出现3H的部位依次为①③②⑥⑤④

    Developed and developing nations can learn from each other seeking a low carbon economy, a Chinese government official said in Shanghai yesterday. “China doesn't lag developed nations in terms of energy saving and green economy”, said Zhou Changyi, director of the energy saving department of the Ministry of Industry and Information Technology.

    “While we can learn many aspects from developed nations, they also should learn something from us, such as water conservation,” Zhou said in a speech during the new Path of China's Industrialization forum at the ongoing China International Industry Fair 2009.

    He said industrialized nations and China are dealing with different issues to combat climate change. The United Kingdom, for example, is concerned about transport, buildings and new energy in reducing carbon emissions. For China, the most urgent task is how to realize new type of industrialization and avoid mistakes that other countries made when they industrialized.

    As such, overseas exhibitors at this year's fair are showing ways to help China achieve low carbon emissions in the industrial section.

    Swiss power and automation technology group ABB called for a stronger focus on product lifecycle assessment, or LCA, which is used to study the environmental impact of a product from the research and manufacturing stage through its usage and recycling.

    Tobias Becker, head of ABB's process automation division for North Asia and China, said LCA is an effective tool in helping manufacturing industries to reduce carbon emissions.

    LCA shows that industrial customers should focus on a product's environmental impact throughout its lifecycle instead of on its initial investment or ready to use stage. For example, a motor's initial investment accounts for only 3 percent of its lifecycle cost, while 94 percent goes to fuel consumption and the rest to maintenance.

    Richard Hausmann, North East Asia CEO of Siemens, said, “The color of future industrialization is green.”

    The Germany Company recently announces that it wants to receive orders worth more than 6 billion Euros (US 8.8 billion) for intelligent net power networks, Smart Grid, over the next five years. Siemens has set a 20 percent market share target for the global smart grid business.

    A smart grid delivers electricity from suppliers to consumers using digital technology, advanced sensors specialized computers that save energy, reduce costs and increase reliability. The United States and China are considered the two biggest markets for smart grid.
