Ketopentose a ketose sugar with five carbon atoms , e . g . ribulose 戊酮糖:一种五碳的酮糖。例如:核酮糖。
Ribulose a 5 - carbon sugar that is phosphorylated to form ribulose bisphospahate 核酮糖:一种五碳糖,可以通过磷酸化形成核酮糖1 , 5二磷酸。
Glycerate 3 - phosphate is the first product of the dark reactions of photosynthesis , formed by the carboxylation and cleavage of ribulose bisphosphate 甘油3 ?磷酸是光合作用暗反应的一种产物,在二磷酸核酮糖的羧化分解后形成。
The most important carboxylase in plants is ribulose bishosphate carboxylase ( rubisco ) , which catalyzes the carboxyation of ribulose bisphosphate , the ‘ carbon - fixing ’ first step in the calvin cycle 在植物中最重要的羧化酶是核酮糖二磷酸羧化酶,它可以羧化核酮糖二磷酸,在卡尔文循环中是二氧化碳固定的第一步。
In these chloroplasts carbon dioxide combines with phosphoenolpyruvate to form oxaloacetic acid , which is transported to the bundle sheath cells , where the carbon dioxide is released , then fixed by the enzyme ribulose bisphosphate carboxylase to form glycerate 3 - phosphate , the first step in the calvin cycle 在叶肉细胞的叶绿体中二氧化碳与磷酸烯醇丙酮酸结合形成草酰乙酸,后被运到邻近的维管束鞘细胞,在那里二氧化碳被释放,后被核酮糖二磷酸羧化酶固定形成3磷酸甘油酸,这是卡尔文的循环第一步。
