Abstract
The quantum efficiency of photosynthetic energy conversion was investigated in isolated spinach chloroplasts by measurements of the quantum requirements of ATP formation by cyclic and noncyclic photophosphorylation catalyzed by ferredoxin. ATP formation had a requirement of about 2 quanta per 1 ATP at 715 nm (corresponding to a requirement of 1 quantum per electron) and a requirement of 4 quanta per ATP (corresponding to a requirement of 2 quanta per electron) at 554 nm. When cyclic and noncyclic photophosphorylation were operating concurrently at 554 nm, a total of about 12 quanta was required to generate the two NADPH and three ATP needed for the assimilation of one CO2 to the level of glucose.
摘要
通过测量铁氧化还原蛋白催化的循环和非循环光磷酸化形成ATP的量子需求，对分离的菠菜叶绿体中光合能量转换的量子效率进行了研究。在715nm处，每形成1个ATP约需要2个量子（相当于每个电子需要1个量子）；在554nm处，每形成1个ATP需要4个量子（相当于每个电子需要2个量子）。当循环和非循环光磷酸化在554nm同时进行时，将1个CO₂同化为葡萄糖水平所需的2个NADPH和3个ATP总共约需要12个量子。
