某些植物光合作用过程除了同学们熟知的C3途径外,还具有图1所示的C4途径。科研人员对C4途径中固定CO2的PEP羧化酶(称为酶a)进行了研究。
(1)据图分析,有C4途径的植物与仅有C3途径的植物在光合作用过程上既有共同点,也有些差异。共同点是二者都能在暗反应阶段中,将CO2固定为________化合物,并利用________阶段储存在________中的化学能,生成糖类等有机物。
(2)研究发现,C4途径中的酶a活性会受到苹果酸抑制;仅有C3途径的植物体内也有PEP羧化酶(称为酶b,不参与CO2的固定),酶b活性也会受到苹果酸抑制。酶a和酶b的结构相似,但苹果酸对酶a的抑制作用小于酶b。科研人员假设,酶a是由酶b的一个氨基酸位点改变而来,从而导致苹果酸浓度较高时,酶a的催化活性高。
①科研人员将酶a的苹果酸结合位点的甘氨酸替换为精氨酸,得到酶a的突变酶,测定得到图2所示结果。据图2推测,酶a的氨基酸替换可能导致酶a的________结构发生改变,使酶a的突变酶与苹果酸的结合力________,从而导致其活性改变。
②科研人员可在另一组实验中进一步证实该假设。若酶b的苹果酸结合位点的精氨酸替换为甘氨酸,请在图3中用虚线补充证实该假设的预期结果曲线。________

(1)图一中代表光合作用暗反应的是,A、B代表的物质分别是__________________,
上图所示代谢过程中,可以发生于高等动物细胞内的生理过程有________________。
(2)通过一定方法将PEPC酶基因导入水稻细胞后,要通过________________技术形成水稻个体。在氧气充足,光照强度为1×102μmol·m-2·s-1时,图一中可进行的生理过程有______________。
(3)根据图二分析,在光照强度为4和12(×102μmol·m-2·s-1)时,转基因水稻的合成O2与原种水稻合成的O2的比值分别为______________________,因此转基因水稻更适合栽种在_________________环境中。
玉米的PEPC酶固定CO2的能力较水稻的强60倍。我国科学家正致力于将玉米的PEPC基因导入水稻中,以提高水稻产量。下列各项对此研究的分析中正确的是
A.核心步骤是构建玉米PEPC基因表达载体
B.通常采用显微注射法将PEPC基因导入水稻细胞
C.在受体细胞中检测到PEPC酶则意味着此项研究取得成功
D.利用细胞培养技术将转基因水稻细胞培育成植株
将玉米的PEPC酶基因导入水稻后,测得光强度对转基因水稻和原种水稻的气孔导度及光合速率的影响结果,如图所示。(注:气孔导度越大,气孔开放程度越高)
(1)水稻叶肉细胞进行光合作用的场所是________,在三碳酸转变为三碳糖的过程中,光反应为碳反应提供的物质是___________________。
(2)CO2通过气孔进入叶肉细胞后,首先与________结合而被固定,该化合物的元素组成为__________。
(3)据图分析,光强度低于8×102μmol·m-2·s-1时,影响转基因水稻光合速率的主要因素是________;光强度为(10~14)×102μmol·m-2·s-1时,原种水稻的气孔导度下降,但光合速率基本不变,此时限制光合速率的是光合作用的_____________阶段。
(4)分析图中信息,PEPC酶所起的作用是__________________________;该转基因水稻更适宜栽种在________环境中。
将玉米的PEPC酶基因导入水稻后,测的光照强度对转基因水稻和原种水稻的气孔导度及光合速率的影响结果,如下图所示。(注:气孔导度越大,气孔开放程度越高)
(1)水稻叶肉细胞进行光合作用的场所是,捕获光能的色素中含量最多的是。
(2)CO2通过气孔进入叶肉细胞后,首先与结合而被固定,固定产物的还原需要光反应提供。
(3)光照强度低于8×102μmol·s-1时,影响转基因水稻光合速率的主要因素是;光照强度为10~14×102μmol·s-1时,原种水稻的气孔导度下降但光合速率基本不变,可能的原因是。
(4)分析图中信息,PEPC酶所起的作用是;转基因水稻更适合栽种在环境中。
玉米的光合效率较水稻的高,这与玉米中磷酸烯醇式丙酮酸羧化酶(PEPC)有很大的关系。如何将玉米的这一种酶转移到水稻等植物上一直是植物生物学家的研究课题之一。但实践证明,常规杂交育种手段很难如愿以偿。最近,有人利用土壤农杆菌介导法,将完整的玉米PEPC基因导入到了水稻的基因组中,为快速改良水稻的光合作用效率,提高粮食作物产量开辟了新途径。
(1)玉米和水稻很难利用常规杂交手段杂交是因为。
(2)获得PEPC基因后,将其导入土壤农杆菌的质粒中,获得重组质粒需要的工具是,请在下框中补充某DNA片段并画出切割形成黏性末端的过程示意图。
(3)导入完成后得到的土壤农杆菌,实际上只有少数导入了重组质粒,可根据质粒中含有的__________筛选出成功导入了重组质粒的土壤农杆菌。
(4)用含有重组质粒的土壤农杆菌感染水稻细胞,即使感染成功,PEPC基因通过一定途径整合到水稻的基因组中,但不一定会表达,原因最可能是_________。
A.玉米和水稻不共用一套密码子
B.水稻中缺乏合成PEPC的氨基酸
C.PEPC基因受到水稻基因组中相邻基因的影响
D.PEPC基因与水稻的DNA基本结构不同
(5)PEPC基因在水稻细胞中成功表达的标志是。
(6)得到PEPC基因成功表达的水稻细胞后,科研人员常采用方法获得转基因水稻植株。

Man:HappyEarthDay!
Earth:Thankyou,butpeoplethinkofmeonlyonApril22nd.
上面是人类和地球的一段简短的对白。请根据对白,结合实际,以MakeEveryDayEarthDay为题写一篇短文。词数:120-150左右。
提示:
1.地球的现状和存在的问题;
2.人们在“地球日”这天用什么行动关爱地球;
3.号召人们把每一天都当作地球日,天天关爱地球。提出你的一些想法和建议。
油菜是一种雌雄同株的重要经济作物,下图表示油菜体内的中间代谢产物磷酸烯醇式丙酮酸(PEP)运输到种子内的两条转变途径。其酶a和酶b分别由基因A和基因B控制合成。科学家根据这一机制培育出高产油油菜,产油率由原来的35%提高到58%。请分析资料回答问题。
(1)图中酶a与酶b结构上的区别是,构成它们的氨基酸的可能不同,并且二者的空间结构也不同。根据图甲中油脂或氨基酸的合成途径,说明基因可以通过控制代谢过程,从而影响生物性状。
(2)已知基因B某一片断碱基排列如右图。其中链是转录链,转录出’链;科学家诱导链也实现转录,转录出’链,从而形成双链mRNA。请写出这个双链mRNA的碱基序列。由于该双链mRNA不能与结合,因此不能合成酶b;但细胞能正常合成酶a,所以高产油菜的油脂产量高。
(3)要想提高氨基酸的产量,除上述方法外,还可采用育种方法,培育出不能合成酶a的植株。

浙江省农业科学院陈锦清教授发现了油菜产油机制:光合作用产生磷酸烯醇式丙酮酸(PEP)运向种子的两条途径,如图11种甲所示。图乙是控制PEPcas酶II合成的基因,其中a链是转录链,陈教授及其助手诱导b链也能转录,从而转录出双链Mrna。并根据这一机制培养出世界上含油量最高的油菜新品系,产油率由原来的35%提高到58%。
请回答:(1)你认为提高油菜产量的基本思路是。(2分)
(2)控制酶II合成的基因的结构单位是。
(3)从乙到合成出甲图中的蛋白质,要经历和两个过程。
(4)据研究,油菜产量提高的原因是双链Mrna的形成阻碍了形成酶II的过程。

(1)酶a与酶b结构上的区别是。
(2)图乙所示遗传信息的传递过程称为;图中结构⑤的名称是;氨基酸②的密码子是;图中④形成后到达此场所是否穿过磷脂分子?。
(3)在基因B中,α链是转录链,陈教授及助手诱导β链也能转录,从而形成双链mRNA,
提高了油脂产量,其原因是。

材料:玉米的光合效率较水稻的高,这与玉米中磷酸烯醇式丙酮酸羧化酶(PEPC)有很大的关系。如何将玉米的这一种酶转移到水稻等植物上一直是植物生物学家的研究课题之一。但实践证明,常规杂交育种手段很难如愿以偿。最近,有人利用土壤农杆菌介导法,将完整的玉米PEPC基因导入到了水稻的基因组中,为快速改良水稻的光合作用效率,提高粮食作物产量开辟了新途径。
(1)玉米和水稻很难利用常规杂交手段杂交的原因是。
(2)获得PEPC基因后,将其导入土壤农杆菌的质粒中,以获得重组质粒,需要的工具酶
是和。
(3)玉米PEPC基因在水稻细胞中成功表达的标志是,该过程包括和两个阶段。
