The entry of carbon dioxide from the atmosphere into the biosphere is mediated by the enzyme Rubisco, which catalyzes the carboxylation of ribulose 1,5-bisphosphate (RuBP) as the entry reaction of the Calvin Benson Bassham cycle (CBBC), leading to the formation of 2 molecules of 3-phosphoglyceric acid (3PGA) per CO fixed. 3PGA is reduced to triose phosphates at the expense of NADPH + H and ATP that are provided by the photosynthetic light reactions. Triose phosphates are the principal products of the CBBC and the precursors for almost any compound in the biosphere.
大气中的二氧化碳进入生物圈是由Rubisco 酶介导的，Rubisco 酶催化核酮糖 1,5-二磷酸（RuBP）的羧化作用，作为卡尔文-本森-巴斯汉姆循环（CBBC）的入口反应，导致每固定 1 个 CO2 形成 2 个 3-磷酸甘油酸（3PGA）。3PGA 在光合作用光反应提供的 NADPH+H 和 ATP 的作用下被还原为三碳糖磷酸。三碳糖磷酸是 CBBC 的主要产物，也是生物圈中几乎任何化合物的前体。
