Abstract
Extracts from chloroplasts of spinach, sunflower and four other reductive pentose phosphate (C3)-pathway species were measured spectrophotometrically with or without a modified preactivation procedure. In all six species this modification yielded Km (CO2) values in the range of 7-15 micron and maximum velocities, at 20 degrees C, of 129-431 mumol of CO2 carboxylated/h per mg of chlorophyll. In general, both the carboxylation and electron-transport capacities of sunflower were somewhat greater than that of the other species, and this is discussed in relation to the superior rates of photosynthesis believed to be displayed by the parent tissue.
摘要
对菠菜、向日葵以及其他四种还原性戊糖磷酸（C3）途径植物的叶绿体提取物进行了分光光度测定，测定时采用或不采用改良的预激活程序。在所有这六个物种中，这种改良产生的Km（CO2）值在7-15微米范围内，在20摄氏度时，最大反应速度为每毫克叶绿素每小时羧化129-431微摩尔CO2。总体而言，向日葵的羧化能力和电子传递能力均略高于其他物种，这一点结合母组织被认为具有的较高光合作用速率进行了讨论。
