考点1:呼吸作用的过程例1为探究酵母菌的细胞呼吸,将酵母菌细胞破碎并进行差速离心处理,得到细胞质基质和线粒体,与酵母菌分别装入A~F试管中,加入不同的物质,进行了如下实验(见下表)。(注:“+”表示加入了适量的相关物质,“-”表示未加入相关物质。)(1)会产生CO2和H2O的试管有,会产生酒精的试管有,根据试管的实验结果可判断出酵母菌进行无氧呼吸的场所。(均填试管编号)(2)有氧呼吸产生的[H],经过一系列的化学反应,与氧结合形成水。2,4-二硝基苯酚
Test point 1: Respiration process Example 1 To explore the yeast cell respiration, the yeast cells were broken and differential centrifugation, to obtain the cytoplasm and mitochondria matrix, respectively, and yeast into the A ~ F tube, adding different Materials, the following experiment (see table below). (Note: “+ ” means adding the appropriate amount of related substance, “- ” means no substance is added.) (1) Test tube that produces CO2 and H2O Yes, Test tubes that produce alcohol have, The results of the experiment can be judged that the yeast for anaerobic respiration. (Fill tube numbers) (2) Aerobic respiration [H], after a series of chemical reactions, combine with oxygen to form water. 2,4-dinitrophenol
