题目详情
为了探究酵母菌所进行的呼吸作用类型,请根据所给的实验材料和用具设计实验。
(1)实验目的:探究酵母菌的呼吸作用类型。
(2)实验原理:酵母菌如果只进行有氧呼吸,即需氧型,则吸收的02量与放出的CO
2
量相等;如果只进行无氧呼吸,即厌氧型,则不吸收O
2
,能放出CO
2
;如果既进行有氧呼吸又进行无氧呼吸,即兼性厌氧型,则吸收的O
2
量小于放出的CO
2
量。
(3)实验材料和用具:酵母菌培养液、带橡皮塞的玻璃钟罩两只、玻璃板两块、l00mL烧杯4个、两根弯曲的带有红色液滴的刻度玻璃管、NaOH溶液、清水、凡士林。
(4)实验方法:将实验材料和用具按照下图配好实验装置。如果想得到实验结论还必须同时设计另一个实验,请在方框内绘出相应的装置图,并注上必要的文字。
(5)请设计一个表格并在表格中写出实验可能出现的结果及相关结论。
题型:实验题
难度:偏难
来源:江苏模拟题
答案
(4)
说明:强调等量的酵母菌培养液和用等量的清水代替NaOH溶液,观察红色液滴的移动情况。

题目详情
(1)实验目的:探究酵母菌的呼吸作用类型。
(2)实验原理:酵母菌如果只进行有氧呼吸,即需氧型,则吸收的02量与放出的CO2量相等;如果只进行无氧呼吸,即厌氧型,则不吸收O2,能放出CO2;如果既进行有氧呼吸又进行无氧呼吸,即兼性厌氧型,则吸收的O2量小于放出的CO2量。
(3)实验材料和用具:酵母菌培养液、带橡皮塞的玻璃钟罩两只、玻璃板两块、l00mL烧杯4个、两根弯曲的带有红色液滴的刻度玻璃管、NaOH溶液、清水、凡士林。
(4)实验方法:将实验材料和用具按照下图配好实验装置。如果想得到实验结论还必须同时设计另一个实验,请在方框内绘出相应的装置图,并注上必要的文字。
