The five prosthetic groups (FAD, [2Fe-2S], [4Fe-4S], [3Fe-4S] and heme group) required for electron transfer from succinate to ubiquinone were unambiguously assigned into the electron density map. Besides, we find there are some electron densities around the Qp pocket at the matrix side and we believe it represents the head structure of ubiquinone, which is proved by the inhibitor bound structure that 2-TTFA just locating at the Qp site. At the same time, we find there is the second 2-TTFA binding site, locating the inter-membrane side. This finding will change our knowledge about the electron transfer inside Complex II and the ubiquinone transfer between Complex II and Complex III, and endow a new role of Complex II in electron transfer chain.

除了对各个电子传递体（ FAD ，[2Fe-2S]，[4Fe-4S]，[3Fe-4S]以及血红素分子）进行精确定位外，我们在该结构跨膜区靠近线粒体基质一端的口袋 Qp 中，发现了一些电子密度，认为是所结合的辅酶 Q 的头部结构，这一点被与抑制剂结合的复合体的结构所证明，在该结构中， 2－ TTFA 恰好结合在口袋 Qp 中，同时，我们还发现了第二个2－ TTFA 的结合位点，位于跨膜区靠近线粒体膜间隙一端的口袋 Qd 中，这个发现具有全新的意义，将影响人们对电子在复合物 II 中传递以及辅酶 Q 在复合物 II 与 III 之间转移的认识，促使人们重新复合物 II 在线粒体呼吸链中的角色。

The formation and evolution of magma have experienced three stages:① thermal fluid led to higher partial melting of lithosphere mantle and then formed hypoalkaline basalt with saturated initial sulfur when ascending asthenosphere contacted with the lithosphere mantle;② the initial magma intruded into the lower crust to form magma chamber, the crystallization of magma produced stratiform-like cumulate, including olivine, hypersthene, augite, magnetite, and then formed residual gabbroic magma with the participance of crustal material;③ the residual magma and ore-bearing cumulate intruded upward successively to shape original mafic complex rocks in Wuxing when the magma chamber cracked.
