一、三碳和四碳植物的差异植物光合作用吸收的CO_2是怎样同化成糖类呢?这个问题在五十年代,由于卡尔文等人的卓越工作已获得了解释.他们在叶绿体中发现有一种二磷酸核酮糖羧化酶(RuDPCase),能使CO_2和二磷酸核酮糖(RuDP)相结合,并形成两个磷酸甘油酸分子(PGA),PGA一部分可转变成糖类、淀粉,另一部分用于RuDP的再生,这一再生过程形成 Differences between one, three and four-carbon plants How does CO2 absorbed by photosynthesis in plants become assimilated into sugars? This problem was explained in the fifties by the excellent work of Calvin et al. They were found in chloroplasts The enzyme RuDPCase, which binds CO 2 and RuDP, forms two molecules of phosphoglycerate (PGA). Some of the PGA can be converted into carbohydrates, starches, The other part is used for the regeneration of RuDP, and this regeneration process is formed
