一.前言能够进行光合作用的绿色植物是地球上生命存在、繁荣和发展的根本源泉。人们很早就知道光合作用的总公式是:6CO_2+6H_2O光(?)叶绿素C_6H_(12)O_6+6O_2 但这仅仅说明了一般的概念,并不能说明CO_2分子和H_2O分子在这个过程中发生了什么变化?碳水化合物和氧气又是如何产生的?叶绿素在光合作用中起什么作用?光能如何转化为化学能?三十多年来,这些同题都是研究和争论的焦点。尤其是空气中的CO_2是通过什么样的途径,最后形成糖类和其他有机化合物;CO_2最初固定在何种物质上,其最初形成的产物是什么,经过什么样的中间转化过程,这都是非常引人 I. INTRODUCTION Green plants capable of photosynthesis are the fundamental source of the existence, prosperity and development of life on Earth. It has long been known that the general formula of photosynthesis is: 6CO_2 + 6H_2O Light (?) Chlorophyll C_6H_ (12) O_6 + 6O_2 However, this only shows the general concept and does not mean that CO_2 and H_2O molecules have occurred in this process What happens? How are carbohydrates and oxygen produced? What is the role of chlorophyll in photosynthesis and how can light energy be converted to chemical energy? These same topics have been the focus of research and debate for more than three decades. In particular, what is the route of CO 2 in the air and finally the formation of carbohydrates and other organic compounds? What is the initial immobilization of CO 2? What is the initial product of CO 2 and what kind of intermediate conversion process Very attractive
