24.(10分,每空2分)(1)C叶绿体类囊体的薄膜上(2)大于(3)叶绿体可利用光照条件下积累的ATP和[H继续还原C3(4)左移【解析】(1)CO2被吸收后与植物体内的C化合物结合而被固定形成C3, NADPH是光反应的产物所以A点处产生 NADPH的具体场所是叶绿体类囊体的薄膜上。(2)B点处钟罩内二氧化碳浓度不再变化,说明植物的光合速率等于呼吸速率,但植物体内存在不进行光合作用的细胞,所以叶肉细胞的光合作用强度应大于其细胞呼吸强度。(3)在B点处奕然停止光照,由于叶绿体可利用光照条件下积累的ATP和[H]继续还原C3,故小麦幼苗的光合速率并不为0(4)若降低钟罩内CO2的起始浓度,则钟罩内的植物达到光合速率与呼吸速率相等时所需要的时间缩短,即B点位置将会左移
