在地球上,几乎一切生物的生存和繁荣都直接或間接地依靠着植物的光合作用来供給它們能量和有机物质。早在十九世紀中叶,人們就已知道光合作用的总方程式为: CO_2+H_2O(?)(CH_2O)~*+O_2 (1) 但是,对于它的詳細机制却至今还不曾全部明了,仍然是生物科学中大家非常关心的重要研究对象。最初,人們对光合作用机制的設想比較簡单,主要是凭着臆测。巴耶尔(Baeyer)于1870年提出的甲醛假說和威尔什塔特尔(Willstatter)等在1918年对这假說的修改,都是把CO_2还原与光化学反应直接联系在一起,并且认为O_2是从CO_2中释放出来的。虽然这些假說
On Earth, the survival and prosperity of almost all living things rely directly or indirectly on the photosynthesis of plants to supply their energy and organic matter. As far back as the mid-nineteenth century, it has been known that the general equation of photosynthesis is: CO 2 + H 2 O (?) (CH 2 O) ~ * + O 2 (1) However, its detailed mechanism has not yet been fully understood, An important research subject of great concern to everyone in the biological sciences. Initially, the idea of photosynthesis mechanism is relatively simple, mainly by speculation. The aldehyde hypothesis put forward by Baeyer in 1870 and Willstatter et al. In 1918 revise this hypothesis by directly linking CO 2 reduction and photochemical reaction, and that O 2 is Released from CO_2. Although these hypotheses
