Chloroplasts, prepared from fresh, prechilled spinach leaves by the method of Jagendorf andAvron, were suspended in Tris buffer (25 μmoles, pH 8.4) containing MgCl_2 (6 μmoles), ADP(3 μmoles), P~(32)-labelled phosphate (3 μmoles), NaCl (25 μmoles) and the different cofactors. Totalvolume of the reaction mixture was 1.25 ml, containing 30-40 μg chlorophyll. Preliminary experi-ments showed that at the low illumination intensity for quantum yield determinations the optimal quan-ties of the co-factors were: PMS or FMN, 0.005 μmole, vitamin K_3, 0.03 μmole, and of the Hilloxidants were: K_3Fe(CN)_6 0.6 μmole, TPN 0.2 μmole. Neon tube with dilute ammoniacal CuSO_4 solution and red-glass filters was used as light source.The wave length range was 620-660 mμ and the intensity was 6-8×10~3 ergs/cm~2/sec. Energydeterminations were made with a blackened constantin-copper thermopile, the absolute energy wascalibrated by the amount of heat produced electrically at the surface of the thermopile. The calcu-lated number of quanta was counter-checked by chlorophyllide actinometer according to Warburg.Light scattering was corrected by the ground glass method of Shibata. Phosphorylation rates weremeasured by ATP~(32) formed according to the method of Nielsen and Lehninger. No incorporation of P~32 was detectable in the dark. To avoid loss of activity preparations were conducted near 0℃ and experiments were completedwithin 10 minutes including isolation of chloroplasts. Representative results are given in Tab. 1. The following conclusions can be drawn. (1) The quantum requirement of cyclic photophosphorylation is between 2.9-6.5 (generally4-5) per molecule of ATP formed, irrespective of the co-factors used,. Although at high lightintensities PMS can be twice as active as vitamin K_3 or FMN, their quantum yields are the same. (2) Same numerical results are obtained with heat deproteinized leaf extract in place of co-factors. (Tab. 3). (3) Non-cyclic photophosphorylation with K_3Fe(CN)_6 or with TPN shows the same quantumrequirement of 4-6. (Tab.1). Apparently one and the same electron transport system is involvedin both types of phosphorylation and there exists probably only one phosphorylation site. However,the possibility of a second easily inactivated site is not excluded. (4) The simultaneously measured Hill reaction requires 9-12 quanta per molecule of O_2evolved with or without photophosphorylation (+ or -ADP, Tab.2). The result corroboratesthose of other workers. It further shows that under the conditions of the present experiment cou-pling is complete (P/2e = 1), and that no extra quantum is needed for the coupled formation ofATP. (5) The quantum requirement of both cyclic and noncyclic phosphorylation increased withdecreasing light intensity within the range used (1.3-6.0×103 ergs/cm~2/sec.) (Tab. 4), whereasthat of O_2 production by the Hill reaction remains constant, thus resulting in a progressive uncou-pling of phosphorylation from the electron transport chain. The relationship between the present results and the quantum requirement of photosyntheticCO_2-reduction is discussed. That at low intensities of illumination used in the present experimentsthe number of quanta required for 2 TPNH and 2 ATP formation equals to that of photosynthesisunder these conditions (~compensation point) indicated that cyclic production of ATP is perhapsnot involved and the extra ATP needed for CO_2-reduction in the Calvin cycle must come fromsome other source, e.g. respiration. That at higher light intensities (several times compensationpoint) the quantum requirement of photosynthesis increases is probably due to the coming into playof the photochemically inefficient cyclic photophosphorylation.

用菠菜叶绿体悬浮液,在红光下(620—660mμ,6—8×10~3尔格/厘米~2-秒)测定同位素P~(32)标记的无机磷酸进入ATP的强度,并根据吸收的光能量换算为形成一个分子ATP所需要的红光量子数。结果指出: (1)循环光合磷酸化作用,不论用何种辅助因素(PMS,维生素K_3,FMN),形成一个分子ATP的量子需要量均在4—5之间(最低一次获得2.9)。叶提取液代替辅助因素,结果亦同。(2)与希尔反应偶联的光合磷酸化作用(希尔氧化剂为K_3Fe(CN)_6或TPN)的量子需要量亦是4—6。同时测定的还原作用指出希尔反应中每放出一个分子O_2,需要8—12个红光量子,表示在试验条件下,二者是完全偶联的(P/2e?1)。没有磷酸化(不加ADP及P_i)时,希尔反应的量子需要量不变,表示偶联的ATP形成不需额外的光量子。(3)光强度减低,则循环与非循环光合磷酸化作用的效率随之降低,量子需要量增加,而希尔反应的效率则不变。从上述结果推论,两种光合磷酸化作用均是通过同一的电子传递系统,在此系统中仅有一个磷酸化部位,除非另有一个部位是极易破坏的。试验结果也对光合作用的量子需要量问题,供给可能的解释。在弱光下光合作用效...

The diploid chromosome number of black carp is 48, the karyotype of whichconsists of 8 metacentric chromosome pairs, 14 submetacentric chromosome pairs, and2 subtelocentric chromosome pairs. The morphology of the chromosome set is charac-terized by very short homologous chromosome pairs of 3.70-2.00μm length range.The total length of the chromosome set is 59.95μm and the number of chromosomearm is 96. This paper also made a review on the comparison of the karyotype of four domesticfishes by different authors.
