1问题1.1中学教科书与高校教科书的表述存在矛盾人教版《生物·必修1·分子与细胞》P.70在介绍物质跨膜运输的方式时认为,葡萄糖不能通过无蛋白质的脂双层;葡萄糖不能自由地通过细胞膜,在载体协助下,顺浓度梯度运输为协助扩散,P.73的课后练习基础题进行了举例说明。P.76的思维拓展补充了葡萄糖可以主动运输进入某种细胞。部分高校教材则认为,葡萄糖分子以简单扩散的
1 ISSUES 1.1 There is a contradiction between the textbooks of secondary schools and the textbooks of colleges and universities. P. 70 Biology and Comprises P.70 describes the transmembrane transport of substances and believes that glucose can not pass through the protein-free lipid bilayer. Glucose Inability to pass freely through the cell membrane, facilitated by carriers, cis-gradients transport to aid diffusion, an example of the post-exercise exercises in P.73 is illustrated. P.76’s mind-set expands that glucose can be actively transported into certain cells. Some college textbooks believe that simple diffusion of glucose molecules
