（12分 每空1分）如图为物质出入细胞示意图，请据图回答([   ]内填字母，       上填文字)：

（1）图中A代表分子        ， B代表                ，D代表                分子。其中，      的种类和数量与细胞膜功能复杂性有关                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 和与细胞表面识别有密切关系的成分是由分子[A]和分子[    ]共同构成的           。
（2）可能代表氧气转运方式的是图中[  ]         ；碘进入人体甲状腺滤泡上皮细胞的过程是图中[  ]        ；钠离子出细胞是通过图中[  ]         。
（3）在人体中，图中ae所示运输方式所需的能量，主要来自线粒体        作用所释放的能量。
（4）从细胞膜的功能特性看，它具有         ,从细胞膜的结构特性看，它具有      。
