题目

下列哪些物质进出细胞时与细胞中的核糖体和线粒体密切相关（ ）①尿素通过细胞膜 ②人的红细胞从血浆中吸收葡萄糖③肾小管上皮细胞吸收原尿中的Na+ ④小肠绒毛上皮细胞吸收氨基酸A. ①② B. ③④ C. ①②④ D. ①②③④ 答案：【答案】B【解析】核糖体是蛋白质合成的场所，线粒体是有氧呼吸的主要场所，为生命活动提供能量。尿素通过细胞膜的方式是自由扩散，不需要载体蛋白和消耗能量，因此与线粒体和核糖体无关，①错误；人成熟时的红细胞从血浆中吸收葡萄糖的方式是协助扩散，该运输方式不需要消耗能量，因此与Chinese buyers used to prize foreign brands, thinking that products made by American or European companies are of higher quality(质量) than Chinese ones. Increasingly, that’s no longer the case.Chinese people born before 1985 generally think that foreign brands are better than Chinese ones, billionaire William Li told Business Insider during a recent interview on CCTV 9. But for who were born after 1985, it is a different picture.“When I first went to the United Kingdom in 1997, I thought that the difference between China and Europe was quite big,” Li said. “But for those born in the 1990s, when they visit Europe or the US, they do not think there is a big difference.”The change in thinking among Chinese buyers is showing up in many markets in China where western companies used to control. A study by Credit Suisse published in March found that young Chinese buyers are increasingly showing a home brand bias.” More than 90% of young Chinese buyers would prefer to buy home appliance brands, according to the study. Meanwhile, home companies producing food, drinks, or personal care products increased their share of the market by 3, 3% over the last ten years to nearly 70%.“Chinese buyers, especially the younger ones, don’t just believe that foreign brands are better. Right now, Chinese buyers think China is good and ‘Made in China’ is not bad at all,” Charlie Chen, head of China buyer research at Credit Suisse, told South China Morning Post in March.The Chinese smartphone market is controlled by home companies—Huawei, Oppo, Vivo, and Xiaomi.
