题目详情
日常生活中人们常用酵母菌发面蒸馒头,某同学想探究酵母菌的细胞呼吸方式,设计了下列实验,请你帮助他完成有关内容:
(1)实验目的:探究酵母菌的细胞呼吸方式
(2)实验原理:细胞的不同呼吸方式释放的能量多少不同,但每种方式所释放的能量中都有一部分以热能形式散失,从而导致细胞周围的环境温度升高
(3)材料用具:酵母菌培养液、质量浓度为0.1g/mL的葡萄糖溶液、液体石蜡油、蒸馏水、保温瓶。温度计、棉花
(4)实验步骤:
①.将质量浓度为0.1g/mL的葡萄糖溶液加热煮沸后冷却备用;
②.取3只保温瓶,编号为A、B、C,并将c瓶设计为对照组;
③.在3只保温瓶中分别加入等量的葡萄糖溶液;
④._____________________________________;
⑤.3只保温瓶中均放入温度计,用棉花轻轻塞上瓶口,并保证保温瓶通气;
⑥.24小时观察并记录3只保温瓶中温度的变化。
(5)预测实验现象和实验结果:
若A瓶温度>C瓶温度,B瓶温度=C瓶温度,则______________;
若B瓶温度>C瓶温度,A瓶温度=C瓶温度,则______________;
若_________________________________,则______________。
(6)某同学也想以酵母菌为实验材料探究相关问题,请你帮他设计探究性实验课题名称。_____________。
题型:探究题
难度:中档
来源:江苏模拟题
答案
(4)④.A瓶中加入适量的酵母菌培养液和液体石蜡油,B瓶中加入与A等量的酵母菌培养液,C瓶中加入与A等量的蒸馏水(A瓶和B瓶可互换)
(5)酵母菌只进行无氧呼吸 酵母菌只进行有氧呼吸(注意和步骤④对照,答案顺序可颠倒) B瓶温度>C瓶温度,A瓶温度>C瓶温度 酵母菌既进行有氧呼吸又进行无氧呼吸
(6)探究酵母菌在不同的氧气浓度下的产物(合理即可)
