    时,胰岛B细胞加快分泌胰岛素。胰岛素会作用于肝脏细胞和肌肉细胞,促进糖原的形成,还会抑制肝糖原的分解和非糖物质转化为葡萄糖,以降低血糖浓度。(2)2型糖尿病患者组织细胞对胰岛素的敏感性降低,称为胰岛素抵抗。2型糖尿病人并不缺乏胰岛素,只是胰岛素无法正常发挥作用,故不能通过注射胰岛素降低血糖浓度。(3)①据分析可知,a组为对照组,处理应是在0h不饲喂PDEA抑制剂、在1h注射缓冲溶液0.1mL。②据分析可知,a组和b组可形成对照,自变量是有无FGF1,由实验结果可知,1h后b组血糖浓度低于a组,故由a组和b组之间进行比较可知,FGF1具有降血糖的功能。③据分析可知,c组与d组形成对照,自变量是有无FGF1。由实验结果可知,在饲喂PDEA抑制剂的条件下,注射FGF1后d组血糖浓度与C组无明显差异,故由C组和d组之间进行比较可知,FGF1降血糖依赖于PDEA。
