(3)在强光条件下,叶肉细胞气孔关闭使CO2吸收受阻,此时过高的O2会在R酶的作用下氧化C5生成CO2,,被称为光呼吸,研究人员通过研究光呼吸拟通过在植物体内构建人工代谢途径进一步提高植物的固碳能力。光呼吸与光合作用相伴发生,其过程如图9所示:图已知R酶具有双重催化功能,既可催化CO2与C5结合,生成C3;又能催化O2与C3结合,生成C3,和乙醇酸(C2)。,实际生产中,可以通过适当升高CO2浓度达到增产的目的,请从光合作用原理和R酶的作用特点两个方面解释其原理:。②研究人员利用水稻自身的基因成功构建了一条新的光呼吸支路,简称COC支路,并成功将支路导人水稻叶绿体,该支路的作用是使光呼吸的中间产物C2直接在叶绿体内代谢释放CO2,请分析该支路能显著提高水稻产量的原因:。
